How To Upload A Picture More Than 30 Mb On Wix
Are you wondering why yous're not ranking well on Google, or why users are not taking activeness on your site? Website speed is a critical user-feel and SEO cistron (affecting bounce rates and rankings), and prototype sizes frequently are the overwhelming performance bottleneck.
I take over ten years of experience building photography websites, and I routinely have to find the right balance between creating an impressive visual bear upon and still crafting a fast & convenient website experience.
In this detailed guide, I'll teach y'all everything you need to know about sizing and compressing images before uploading them to your website, what tools to use, how to examination your site's speed, and much more.
You'll observe straightforward and actionable tips on how to optimize images for the web and how to improve your site's operation scores rapidly, with tons of examples and resources, and a comprehensive FAQ at the finish.
This guide is written with photographers in mind but applies to any responsible website owner looking to improve their website'due south load times.
Why care well-nigh epitome sizes & website performance?
People look websites to be really fast. Google does too.
However, most top photography websites out in that location are wearisome:
Source: Photography Websites Report: Stats & insights from the websites of the world'south acme 100+ photographers
Website performance has become an essential SEO and user-experience factor in contempo years, as connection speeds have greatly improved. Whatsoever long delays in page load times might crusade your website's visitors to lose involvement and leave.
And with half of your visitors likely using a mobile device, delivering optimal image file formats & sizes is disquisitional. Otherwise, your difficult-earned traffic decreases, and your Google rankings eventually drop too.
How practice you know if your website has paradigm-related performance problems?
Simply test your site with costless tools similar Google PageSpeed Insights or GTMetrix or Page Weight by imgIX, and yous'll probably run into bug like these:
Follow this guide for detailed instructions on how to fix those performance problems. Part 4 explicitly covers all the image-related page speed "opportunities" listed in Google PageSpeed Insights.
So if you intendance nearly your site performance (and, in turn, its SEO), y'all need to control the size of your images.
Lowering file sizes while maintaining acceptable quality is the primary goal of optimizing images for website performance. Smaller files lead to faster page loads and improved user-experience & SEO.
But how should you resize and compress your photos before uploading them to your site? How can y'all automate this process? And what file formats should you use?
Let's deconstruct the iii primary guidelines for reducing prototype file sizes (without sacrificing quality likewise much, of course):
one. Best epitome sizes for websites (dimensions in pixels)
It all starts with finding out the correct prototype dimensions needed for your pages, to assist you better set them on your computer first. Uploading big images to your site, without regard to the actual size they're existence used at, is what causes huge operation issues.
Here are detailed website image size guidelines (updated for 2022).
Only first, regardless of file formats (JPG, PNG, GIF, TIF, etc.), yous should never upload high-resolution images to your site only for display purposes.
Even if your website is only displaying them at a smaller size, the URL for the original images can often be reverse-engineered from the source code, and your images can get stolen. Plus, large images accept a lot more time to upload and are slower to optimize.
At the very least, use a plugin like Resize Prototype After Upload or Imsanity (if using WordPress) to take care of resizing for you, and also do a bulk resize of all your previously uploaded images while you're at it.
The simply exception is if yous're using a secure photography-specific platform which likewise allows selling prints & image licenses (similar PhotoShelter or SmugMug).
These services need the highest image size y'all take to let printing at larger sizes and skilful-enough quality. Likewise, these platforms forestall epitome theft past automatically resizing images to a smaller size when displayed on the web.
Otherwise, if yous're only displaying images in a portfolio or a weblog mail service, never use images at their maximum dimensions.
What practice you mean by "image size"?
By "image size", we're referring to the image pixel dimensions (width and height in pixels), or the paradigm file size (KB or MB).
But we are Non referring to the image size in inches/cm or to the image DPI. On the web, DPI is irrelevant and only pixel dimensions thing!
How to determine the correct image dimensions for your website
For optimal website performance, images should exist equally large as needed to fill their "containers", based on your page layout. For case, slideshow images are ordinarily wider; blog images are medium-sized (at a width equal to the page width minus the sidebar); thumbnails are smaller, etc.
So it's crucial to make up one's mind image dimensions first, to know how wide your content expanse is on your site. Yous tin can employ a "page ruler" browser extension that helps you take the measurements, or if you accept feel, use the developer tools built into your web browser: right-click on any page element and click "Inspect"
Here are instructions for finding the chemical element selector in other browsers.
Then use the element selector tool in the toolbar and hover over the image or content area you're interested in:
In this example, the column above needs an image of at least 585 pixels in width.
I say "at least" because images probably need to be larger than that to account for high-density "retina" screens in mod devices, so they look extra sharp.
Permit'due south consider a few scenarios:
a) Image sizes for total-width slideshows
For full-width slideshows (that automatically stretch to the full size of the browser), I recommend going for 2560 pixels in width, which is the standard resolution width for 27″ and 30″ monitors.
Images can have whatever height you need, to create an attribute ratio you're comfy with. For instance, full-page slideshows that are popular on wedding photography sites keep the original attribute ratio of images. Other sites utilize a slideshow that still takes the entire width of the page, simply that'south shorter in height (leading to an attribute ratio of around 3:1)
Here are examples of such "panoramic" slideshows from photography websites:
By the style, please reconsider using a homepage slideshow in the showtime identify.
And so for any images that bridge the entire width of the browser, images should be 2560 pixels in width, and whatever height you prefer (depending on whether you want to keep the original aspect ratio of your photos or become for a more than panoramic ingather).
Use 2500px if y'all desire a round number :-)
This is not a scenario where we need to double the image dimensions for retina screens, because that would create huge 5000px images (with big file sizes besides, not to mention the risks of image theft).
For smaller slideshows that don't take upwards the entire width of the page, just maybe just a percentage of it, adjust the required image size accordingly (maybe 2000px, or 1800px, etc.)
b) Gallery image sizes (and thumbnails that enlarge in a lightbox view)
Thumbnail galleries are special scenarios where you ignore the size of your thumbnails, and instead, brand sure images are big enough when enlarged.
Past "lightbox view", I'1000 referring to a grid of thumbnail images that, when clicked on, open in a total-screen slideshow (commonly with a semi-transparent overlay underneath):
Since those images will open up in a full-screen view, I recommend sizing them to at least 1500 pixels (on the longest edge), so they look large enough on desktop and tablets.
You can fifty-fifty take them upward to 2000 pixels if yous want, for some extra "wow factor", but unremarkably not more that.
On mobile devices, images become resized past the browser anyhow, and that 1500px size is enough to look crisp on smartphones with loftier-PPI "retina" screens too.
Vertical/portrait images can be even smaller, with a maximum height of 1200px (like 800×1200 pixels for a 2:three vertical image, or 900×1200 pixels for a 3:iv vertical epitome).
Restricting the prototype dimensions like this volition go on the file size reasonably pocket-sized, resulting in a faster image loads (if the slideshow allows navigating between images using side arrows, bullets, swiping on mobile or keyboard arrows on desktop):
1 important technical aspect hither: your website theme/template should ideally be smart plenty to use smaller-sized images for the thumbnails, and their higher-sized versions for the lightbox mode.
Notice how this site'south theme uses the total-scale prototype in the link (which gets used when opened in the lightbox view/slideshow), and smaller sized image files for smaller screens at different breakpoints.
Choosing a quality WordPress theme can do all this for you.
c). Platonic sizes for blog images or other static images used in page layouts
Bold that your blog images don't need a click-to-overstate (aka "lightbox") capability, images should exist sized depending on the width of that column or content surface area.
Permit's take an individual blog postal service case:
Using the methods described to a higher place, you lot can make up one's mind the actual width of the content area by measuring whatsoever paragraph of text, for example:
Or if you already have images, you tin can make up one's mind what size they're beingness resized to by the browser:
Alternatively, y'all could utilize a browser extension similar View Image Info (backdrop) to get that same info:
Armed with that knowledge (825 pixels in this instance), you can now double that size to accept into business relationship retina screens (so 1650 pixels in width here).
Depending on your specific site theme, and your image theft risk-tolerance :-), you tin can lower that number downwardly to a more reasonable 1200 pixels on the longest edge (and so 1200px in width for horizontal images, or 1200px in meridian for vertical ones, maintaining their original aspect ratio of class).
The same controlling applies to smaller images used as thumbnails (which don't need to be enlarged).
For example, your site might display some thumbnails as your "Featured galleries":
Knowing that they become displayed at 260×174 pixels in width based on your page layout, yous'd upload images at twice that size: 520×348 pixels.
Once you lot've figured out what pixel dimensions your images should have, you lot can get-go preparing them in your photo editing software of choice. Which leads usa to the 2d most important attribute…
2. Platonic prototype file types, quality & pinch levels
a) Exporting & compressing JPG images
Regardless of the photograph editing software that you're using, you nearly never need to export images at 100% (in the quality slider). Choosing something like 60 or 70 gives you good-enough quality for much smaller file sizes (sometimes yous can run across a 5:1 reduction in file size without any perceived quality loss).
I recommend Non using Lightroom'southward "Limit file size to…" option instead of the quality slider, because you could end up with some very pixelated images, considering of how the JPG algorithm works.
Photos with more color and finer details (similar copse/foliage) often naturally have larger file sizes, and setting a hard limit tin can consequence in over-compression.
Use this option but when you truly know what you're doing.
Only when you starting time to become lower than 50-60%, exercise you lot offset getting visible artifacts due to the high file pinch. But between 100 and lxx-80, the quality difference is unnoticeable, while the divergence in image file size is enormous.
For best results, experiment with diverse quality settings for your images, and don't exist afraid to punch down the quality – the visual results are ofttimes very good and the filesize savings can be quite large.
(source: Google Web Fundamentals – Image Optimization)
Hither's a simple experiment I did with exporting an image at different quality levels:
A similar principle applies if y'all're exporting images from Adobe Photoshop.
If yous're using the latest version of Photoshop CC, be sure to use their new consign dialog nether File > Export > Consign Equally…
That usually outputs better results than using File > Export > Save for Web (Legacy), and definitely ameliorate than using File > Salvage As…
Then do some experimenting and choose a pinch level that you lot're comfortable with.
When comparing images (100% quality vs. sixty% quality, for example), don't forget to preview them at the dimensions at which they'll show upwards on your site. The goal is non to compare zoomed-in 1:1 previews of loftier-res files (where you're more likely to notice JPG artifacts), but to compare images at "realistic" pixel dimensions (which usually look sharper and without any meaningful visual differences).
Once again, most people find 60% – 70% an acceptable compromise between image quality and file size.
Most photographers will know that images with gradients pose a big trouble hither (walls, skies, groundwork colors). At depression compression levels, you can offset to see the lines in the gradients (aka "banding"), a sign that you demand to heighten the quality (to 80-xc%).
In the finish, the images on your site should not go beyond 500 KB (= 0.five MB) in file size.
And e'er salvage JPG images in the sRGB colour profile, which is what about browsers understand, to avert any image colour integrity problems.
b) Using PNG/GIF/SVG file types for graphics with solid colors
Besides your photographic work, your website likely contains various other graphical elements: logos, small icons, banners, separators, video thumbnails, etc.
Instead of using JPG, any graphics that comprise areas of solid colour (created by you lot in Photoshop or other tools online) could be ameliorate saved in other lossless file formats (with absolutely no perceived visual differences). PNG, SVG, and GIF formats can piece of work well in such cases.
Unproblematic image format decision tree (source)
While PNG and GIF file formats are quite popular, SVG is somewhat of a mystery for near photographers.
SVG, which stands for "Scalable Vector Graphics", is really a text file that describes lines, curves, shapes and colors in a linguistic communication chosen "XML".
Without relying on a pixel-grid, SVG files have the great benefit of being infinitely scalable without whatsoever loss in quality. And because they're text-based, they usually take smaller file sizes, and they tin can be manipulated with CSS lawmaking.
Good SVG usage scenarios are: logos, icons, illustrations, drawings, etc.
You tin can generate SVG files using Adobe Photoshop or Illustrator.
"Finally, in one case you've determined the optimal prototype format and its settings for each of your assets, consider testing additional variants encoded in WebP, JPEG2000 and JPEG XR. Both of these formats are new, and unfortunately are not (nonetheless) universally supported by all browsers, but they can nonetheless provide meaning savings for newer clients – for example, on average, WebP delivers a 30% filesize decrease over a comparable JPEG image." (source)
WebP appears to be the "winning" paradigm file format of the future, and many optimization plugins (listed beneath) have started supporting it: they can assist you automatically generate WebP versions of your images and and then automatically deliver them to compatible devices.
Permit's have one of the graphics I used above as an case:
You have to exam this out yourself, on a per-image basis. Ever try to use lossless file formats (like PNG or GIF) when you can get smaller file sizes. Merely like I said, this only holds truthful for graphics with solid colors. Whenever you endeavor this same experiment with a regular photo (taken with your camera), JPG usually wins (by a lot).

iii. Optimizing images for the web using extra pinch tools & plugins
OK, so you're ready to upload images to your website.
Even if you correctly set the right pixel dimensions and compression levels when exporting your images (using Photoshop or Lightroom, for example), the post-obit tools tin can accept prototype optimization to the next level.
It's important to note here that you don't necessarily have to compromise on quality hither, you can fix these extra tools to perform a "lossless" optimization.
Let's take this quote I once received from a photographer on this topic:
"If the images out of the processing software (e.g. Lightroom) are already downwardly to their lowest acceptable compression visually, I constitute using plugin reduces file size but likewise reduces the noticeable visual quality. I'd rather sacrifice kb size and proceed visual appeal."
But even when going for a lossless compression blazon, where the results are pixel-identical to your original images, these tools tin reduce file sizes as much every bit possible, along with many other useful features that help make your website faster.
It comes down to personal preference: choose the compression level that best suits your workflow and your goals for the website.
Here are the 3 compression options available in the ShortPixel plugin:
Similarly, Imagify has the following compression levels to choose from:
Image optimization is both an fine art and a science: an art because there is no one definitive answer for how to all-time compress an individual image, and a scientific discipline because there are well-developed techniques and algorithms that tin help significantly reduce the size of an image.
(source: Google Web Fundamentals – Epitome Optimization)
Let'southward explore some tools yous can employ to optimize images for the spider web:
a) WordPress plugins
If using WordPress, you're in luck. There are a bunch of great plugins that do a lot of work for you, automatically. They accept every epitome you upload and then compress it to optimize the file size.
Here are some popular image optimization WordPress plugins:
- ShortPixel (my current recommendation)
- Imagify (no longer has old credits, unfortunately)
- Smush Epitome Compression and Optimization
- EWWW Prototype Optimizer
- Kraken
- Robin Image Optimizer
- Optimole
- Optimus (limited to 100 KB images in the free version)
- ImageRecycle
- Optimizilla
Out of all of them, I currently recommend ShortPixel for their peachy features & customer support:
A free account with them gives you lot a decent monthly quota, and you can go a premium program to let optimizing many more than images per month if yous need to.
Here's a video I created on how to configure the ShortPixel plugin settings:
You tin as well pay a 1-time fee to become a bunch of former image optimization credits (useful when using their bulk optimizer to get through your existing Media Library).
In this case, make sure you lot properly configure the plugin settings to merely choose the thumbnail sizes that matter to your site. Otherwise, those ane-fourth dimension gear up of credits will go by actually fast.
In fact, it's a good idea to set the correct image sizes commencement (nether Settings > Media) based on your website template width, or on your weblog layout/width):
- set the "thumbnail" size to however big needed by prototype grids on your site
- gear up the "large" size to the width of your content surface area in a default page template (usually 1200-1300px)
- and set the "medium" size to exist somewhere in the middle
And then regenerate all past thumbnails, and then, finally, do a bulk optimization of your entire Media Library.
Shortpixel'due south "sleeky" optimization offers a good compromise between image quality and file size, only you lot tin switch to the "lossy" or "lossless" optimization levels as you see fit.
"So, what is the "optimal" configuration of lossy and lossless optimization? The respond depends on the image contents and your own criteria such equally the tradeoff between filesize and artifacts introduced by lossy compression: in some cases you may desire to skip lossy optimization to communicate intricate particular in its total fidelity, and in others you may be able to employ ambitious lossy optimization to reduce the filesize of the image asset. This is where your own judgment and context need to come into play – there is no i universal setting." (source)
If you lot tin can, I recommend bulk-optimizing all your past images (from the WordPress media library):
Here'due south how ShortPixel stacks upwardly confronting Imagify, Ewww and other image optimization tools.

b) Other image compression tools
If yous don't use WordPress, you can try other desktop or online tools to "clasp" your images.
Here are some of the all-time resources I could observe online:
- JPEGmini Pro (paid, Mac & Windows + Lightroom & Photoshop plugins)
- JPEGmini is one of the most pop tools with photographers. I do not think information technology introduced much amend results than using a expert WP plugin, and some photographers told me they're not completely satisfied with the paradigm file sizes information technology generates (especially for spider web utilize).
- ShortPixel (web version of what their plugin does)
- Imagify (web version of what their plugin does)
- ImageOptim (free, Mac)
- Optimage (costless, Mac)
- PNG Gauntlet (free, Windows)
- Trimage (gratuitous, Linux)
- ShrinkMe (complimentary, online)
- Majority Resize Photos (free, online)
- Compressor (free, online)
- TinyPNG (costless & paid, online) (works with both PNG and JPG images)
- Photo Size Optimizer (free & paid, Mac) (formerly known as ImageMini)
- Lossless Photo Squeezer (free & paid, Mac)
- Google Squoosh (free, spider web app, one image at a time)
- Shopify users can apply these apps: Beat out.pics, Minifier
- more image optimization tools hither
Once again, don't forget to optimize your existing site images
Besides creating a squeamish epitome optimization workflow for your future uploads to the site, yous should also use the tools above (like ShortPixel'south Majority Optimization feature) to scan and optimize your by photos.
Alternatively, a nifty piddling tool that tin can quickly analyze and compress your already-published photos is Image Optimization Tool (by WebsiteToolTester), the procedure is quite unproblematic:
i. Paste the URL of the page y'all want to analyze:
2. Become a list of pictures that can/should be optimized:
3. Click to download the optimized images (as a ZIP annal) that you lot tin supersede the erstwhile images with.
four. Website performance testing: See how epitome sizes touch on your site'south speed
Armed with all this image optimization knowledge, let's now review your site'southward performance to see where you lot stand.
Before diving into image-specific testing tools, know that y'all can gain a lot of insights from these two popular website speed testing tools: Google PageSpeed Insights and GTmetrix.
They do a pretty good job of outlining technical problems with your site's functioning, including poor use of images (images too big, wrong file formats, uncompressed files, etc.)
As an experiment, I'grand reviewing a sample homepage using a 5-image slideshow along with some extra text and a smaller single image below.
The page intentionally does a lot of things incorrect in order to highlight its problems in testing tools:
- no operation plugin whatsoever
- no lazy-loading feature
- high-res JPG images uploaded, uncompressed
The Google PageSpeed Insights report outlines some of import performance opportunities that yous might come across on your ain site:
Permit'southward accept them one past one to deconstruct their meaning:
a) Properly size images
In this instance, Google is telling you that you shouldn't upload loftier-res files to your site so simply brandish them at a smaller size on the page. While the browser is responsible for resizing the epitome to fit its container, it still has to download the full file from the server, taking up more time and bandwidth.
That means that images should only be sized every bit big as needed by your folio layout (see part 1 of this guide).
Some WordPress plugins aim to automate this process by detecting the user's screen size and serving properly scaled images:
- ShortPixel Adaptive Images (which is a separate plugin from their main ShortPixel plugin) serves smaller image sizes using their CDN, so don't employ information technology if ranking in Google Images is important to you. Why? Because using an external CDN might impact SEO. It's complicated.
- Adaptive Images for WordPress is a free alternative that generates smaller image sizes directly on your site (only for mobile devices, you can specify the breakpoints)
At the very least, utilize a plugin like Resize Image Subsequently Upload or Imsanity to automatically resize high-res images to a more than "decent" maximum size, only be aware that they both strip EXIF metadata from resized images.
Or better nonetheless, utilise a plugin like ShortPixel or Imagify to both restrict maximum image sizes and yet keep EXIF tags:
b) Defer offscreen images
On the showtime folio load, only a few images are likely to exist seen straight away (those that are "above the fold"). Loading all the other ones (lower down the epitome) can be delayed until other disquisitional site resource accept finished loading.
This process is called "lazy loading" and is a critical step in website speed optimization, especially when considering how image-heavy pages load on mobile devices (with slower connection speeds).
Fixing this issue is relatively unproblematic. Only use an image optimization plugin that supports the lazy loading feature:
- Smush has the feature congenital-in
- ShortPixel has information technology's accompanying "ShortPixel Adaptive Images" plugin for lazy loading and other cool features
- Imagify works well with the gratuitous "Lazy Load by WP Rocket" plugin. My favorite performance plugin – WP-Rocket – has the characteristic born.
- The "a3 Lazy Load" plugin is specifically designed for this characteristic
c) Serve images in adjacent-gen formats
JPG is the dominating image file format on the web, just information technology doesn't hateful it's the best. WebP, in detail, is a format that'southward promoted by Google and that's slowly getting traction.
But your JPG-based photo capture and upload workflow will likely stay the same for a few years to come, especially since WebP browser support is not yet that good.
But what y'all tin practise is use a plugin that can generate WebP images and and so automatically evangelize them to compatible browsers:
d) Efficiently encode images
Google determined that your paradigm file sizes could be smaller, even with a pixel-perfect lossless pinch. That means that your electric current images are not optimized to the max.
Simply use a good image optimization tool (like the ones mentioned throughout the article) to handle the image compression for you, at the quality level y'all're comfy with ("lossless" for photography perfectionists, "lossy" for everyone else).
Permit's now look at the GTmetrix report:
Update: Since writing this article, GTmetrix changed their reports and now focus more heavily on Core Spider web Vitals. Only the bones principles of making a website fast remain the aforementioned.
a) Serve scaled images
It's similar to the "Properly size images" event in Google's examination. You can run into that GTmetrix identified the right size at which those images were beingness displayed on the folio.
Make sure your photos are correctly sized based on your folio usage (see office 1 of this article).
b) Optimize images
Similar to the "Efficiently encode images" effect in Google's test.
Use a good epitome compression service/tool.
Implement as many of the image optimization tactics explained higher up, and you'll see considerable improvements in the performance tests:
Alternatively, you can apply this swell new operation tool: Page Weight by imgIX
Type in your URL, and it analyzes how images bear upon your page load speed; hither's an instance:
Please be enlightened though that it can throw "false negatives": the report can sometimes tell you that yous should resize a specific prototype to a smaller size than what your site actually needs.
The tool suggested an image dimension of 335×251 pixels, when in fact we tin measure out that the site displays it at a larger size. That's why it'southward important for you to manually decide the right dimensions for your images (see role 1)
5. Website image size troubleshooting tips & FAQs
This all sounds besides complicated. Can yous just tell me what to do? What size should images be for my website?
All correct, hither's a recap.
First of all, follow these vital spider web image size standards:
- Never upload high-res files to your site (unless you're selling them as prints or licenses). Only pixel dimensions matter on the web, you can ignore DPI.
- Images that finish upwardly in galleries & portfolios tin can be sized at effectually 2000px on the longest side, maybe even smaller for vertical images (let's say 2000px in width for horizontal images, and 1500px in peak for vertical images).
- Smaller images used throughout your site (site logos, client logos, portraits, other graphics), should be sized as large equally they're displayed (which yous tin notice using your browser'southward developer tools mode).
- Save images at a medium quality level to lower file sizes (like threescore-70% for JPG files). Some images piece of work amend in other file formats (like PNG or SVG), yous accept to test.
- Always use an image optimizer tools/plugins (commonly using a lossy method – not lossless)
- In the end, all images on your website should have less than 500 KB in file size!
Beyond those guidelines, here are iii different strategies for optimizing website images, depending on your level of involvement:
a) The "I'm very busy" solution
For photography-specific platforms like PhotoShelter or SmugMug, no action is needed.
WordPress users, install either ShortPixel or Imagify, and configure it to:
- automatically optimize images on upload
- backup original images
- enable lossy/normal compression
- resize large images (to a max of 2000px)
- generate WebP Images
- optimize retina (for which y'all also install the WP Retina 2X plugin, they work really well together)
- activate the Retina prototype optimization in the Advanced tab of the ShortPixel Settings
And so, using the plugin you just installed, do a bulk optimization of your past images.
Depending on the number of images in your Media Library, y'all can get a one-time plan to handle all your images in one go.
For other platforms (SquareSpace, Wix, etc.), set the images correctly on your computer, past following the guidelines above, and then also run them through a free tool like these.
b) The "I accept time, merely my budget is zero" solution
Yous kickoff by preparing images on your computer at the correct pixel dimensions and a compression level you're comfy with.
Sure, WP plugins can exercise the resizing and compression automatically, but the upload procedure is much slower that way, and it's better to be in full control over the quality of your images.
When compressing images on your figurer first, y'all can double-check if the quality level is good plenty (with a small file size, but without any visible racket or JPG artifacts).
Evidently, Adobe Photoshop or Lightroom don't autumn nether the "free tools" umbrella, they're quite expensive in fact, but about photographers have and use them. If you don't, here are some gratis image editing Lightroom alternatives you could use, along with some free image compression tools.
When yous upload the images to your site, you'd yet utilize a plugin like ShortPixel or Imagify (or some of the other free spider web tools if y'all're not on WordPress), but you'd configure them to do a lossless compression on your images, that's information technology.
Both plugins have free tier options, you're simply limited to a monthly quota. Once you lot've optimized a certain number of images in a calendar month, you'll have to wait for the side by side month for the quota to reset.
c) The "I want it all to be perfect" solution
If website functioning is of utmost importance to you, here's an overview of the "perfectionist" workflow:
- Determine the pixel dimensions needed, based on your website blueprint (see part 1 of this guide)
- Export your images (at the previously-adamant dimensions) at a quality level yous're OK with. This might crave doing some examination runs and playing around with the export quality settings, until you've found the "middle ground": a high-enough compression level so that file sizes are small, simply not too much compression to start introducing visible artifacts. Normally, that's effectually a 60-70% quality level, only it depends on your types of images.
- At this betoken, you could either use a WordPress plugin direct or utilise stand-alone image pinch tools if you're non using WordPress.
- For WordPress users, choose between ShortPixel and Imagify, configure them as I outlined above. Too, install the free WP Retina 2X plugin to help with creating retina images.
- Start uploading the images to your Media Library. The site will now automatically compress your images.
- Exam and re-examination your site's speed. Cheque out the "Website testing tools" section.
Do I need to size images in three (or more than) different means for people on different size devices?
No. Your website platforms should do that automatically for you.
For example, here's what WordPress does:
1. Whenever you upload an image, it as well generates iii other image sizes alongside your original: thumbnail (150×150 with cropping), medium (max 300×300 without cropping), large (max 1024×1024 without cropping)
I recommend changing those defaults to suit your site'due south template blueprint. Look at how large your thumbnails are being displayed in grids, and ready that as the "Thumbnail size" (and consider disabling the "Crop" selection to respect the initial aspect ratio of your images).
And if you know what you're doing, you lot can add other automatically-generated image sizes using a plugin like Uncomplicated Image Sizes (link). Subsequently making changes, be sure to regenerate all thumbnails again.
2. WordPress then adds some special code to the site to load images in a responsive manner, belling the browser to use the proper paradigm/thumbnail size depending on the screen size:
Then unless your platform completely doesn't support responsive images, you should just upload one unmarried epitome version, then permit your platform, your template/theme, or a plugin do the rest of the work.
How nigh adding a simple table with all the prototype sizes?
A tabular array is but possible for total-screen images, and fifty-fifty then, just the desktop versions matter (2000px on the long edge). For mobile and tablet, the WordPress theme should be smart enough to automatically generate smaller versions of the images depending on the device size. Information technology's not something that the website possessor needs to ready beforehand.
As for whatever other images on the site (not total-screen images), a table is non possible considering paradigm sizes depend on the site design. For example, one site might have a blog area designed to be 800px wide, then images need to be 800 x ii = 1600px broad (for retina screens). But some other site might have the weblog at 600px wide, then all that changes. That'south why there are no stock-still values I can put in a table.
Wix recommends uploading images of AT To the lowest degree 3.000 pixels, should I do that?
Absolutely not.
Wix does indeed recommend uploading high-res images, which the platform them automatically compresses and resized depending on the template needs.
If the image is used in a large slideshow, Wix generated a larger JPG paradigm. If used equally a thumbnail, a smaller-sized JPG is generated.
And that'due south all neat, website performance is mostly taken care of.
Simply… people can yet get access to the high-res images (if they know how to tweak the URLs of those images).
I tested this out on the Wix site of a popular photographer (which I won't mention here): the homepage was displaying a single portrait image at effectually 900px, just by looking in the source code and tweaking the image URL, I was able to load the original paradigm sized at 5.792 x 8.688 pixels (and 17.84 MB in file size)!
And so for prototype protection purposes, simply upload compressed images at the pixel dimensions needed by your page layout (upward to a maximum of 2500 pixels on the longest border).
I've optimized my images, and they're all below 500KB, some even below 200KB, but my page is still tedious to load. What gives?
Images are just one gene when information technology comes to website performance. Other bug might exist affecting your page load speeds:
- tedious hosting server
- issues caused past faulty plugins
- javascript errors
Just when it comes to images, don't forget that it's as well a matter of quantity: yous should limit how many images you have on a single folio:
- for portfolios, information technology's a skilful idea to narrow your pick down to your absolute-best photos (read more on this topic)
- galleries should utilize pagination to break them downward to 25-50 thumbs per folio
- for main blog index pages, only show web log mail excerpts (and featured images) instead of listing the entire mail contents (here'due south why)
- on individual blog posts, try to limit the number of large images to 10-15, there'due south commonly no need to take more. Wedding photographers, in particular, accept the bad habit of treating blog posts every bit portfolio pages, listing a ton of images from each issue.
Besides paradigm optimization bug, what WP caching plugin practise you recommend?
Without a caching plugin, for every page on your site, WordPress needs to generate the final HTML lawmaking based on tens of PHP templates and functions (from the WP core, theme and all plugins). Caching solves this by saving a copy of the final HTML code, and delivering that to browsers rapidly.
For this, I highly recommend using WP Rocket, information technology'south a premium plugin (so it's non gratis), but it's incredible powerful and like shooting fish in a barrel to utilize, you can't go wrong with it.
Hither are just a few of its performance options:
Find it also expensive? Email me to inquire for a few up-to-engagement costless alternatives, happy to assist. I can install and configure the WP Rocket plugin (with a premium license) every bit part of my performance optimization service.
I followed instructions, but my images still look too "soft" on the site. What should I do?
When an image gets resized, information technology loses some sharpness. This can happen at two different stages:
1. When you export images
Later exporting images on your computer, make sure they look well at that place before uploading them to the site.
If they're too soft, you might need to employ some output sharpening (low, standard or high) when exporting them:
2. When the browser resized the images on the site
That usually means that you haven't correctly uploaded images at the right pixel dimensions, and the browser is having to resize them on the fly to the size needed by your theme/template.
The "soft" expect is more than pronounced when but a small corporeality of resizing is needed. For example, if you lot uploaded an 800px image and your blog template only displays it at, let's say, 799px, the paradigm will await very blurry.
Why? Because browsers do a sloppy pixel interpolation job considering they prioritize speed over quality. The "image-rendering" CSS belongings aims to permit more control over this process, but browser support is limited.
That'southward why it'south important to correctly determine the correct pixel dimensions needed for your images (see function ane)
What about retina screens?
I took high-PPI "retina" screens into consideration when talking most paradigm dimensions (in part 1).
In short, hither are the best-practices of image optimization for retina screens:
- when because how to size your images (depending on their usage on your site), it's OK to double that size so they expect actually crisp on retina devices
- but in that location'due south a limit, I don't recommend going in a higher place 2500 pixels (on the longest edge) unless yous really know what y'all're doing. For case, a 27″ iMac has a resolution of 5120 x 2880. You wouldn't really have images that large in a total-screen slideshow, would you? They'd load terribly slowly (due to their large file size), and ill-intended people can also steal them from your site.
- when preparing double-sized images, information technology's good do to save them with "@2x" at the terminate of the filename (earlier the file extension)
- for WordPress sites, the golden standard is using the WP Retina 2x plugin which helps yous generate larger-sized thumbnails in the admin surface area and then delivers them automatically to capable devices.
- by the style, WP Retina 2x works well with the ShortPixel Optimizer ;-)
Should I let plugins automatically strip EXIF metadata from my images?
Removing Leave metadata tin indeed help reduce file sizes fifty-fifty further.
The squad behind ShortPixel did a quick study on over a thousand images and concluded that removing EXIF information leads to files that are 8.five% smaller.
Some image optimization services let yous choose whether to strip the metadata; some don't. In practice, the portion of the filesize taken up by metadata is quite modest with larger images, but it can make a big departure, proportionally, for smaller images. (source)
At the moment, information technology's not articulate if Google actually uses whatever EXIF data as a ranking factor:
SEO experts say that Google might use EXIF data in the hereafter (for finding the original source of an prototype, for showing geo-data / GPS coordinates to help with local rankings, and for showing EXIF-based filters in Google Images), but it'due south unclear when.
Until Google makes information technology all more than articulate, I personally think it's all-time to keep the epitome metadata. The 8.five% file size reduction is not worth the potential SEO benefits.
I need to fix some of my old images. Should I just delete them and upload new ones?
Deleting old images from your Media Library is risky because whatsoever references or links pointing to them might get cleaved. So only delete them when you're sure they are no longer being used anywhere on your site.
Uploading new (similar) images can as well get out of control quickly, over-crowding your site'due south Media Library.
A cleaner method for WordPress site owners is to use the gratis "Enable Media Replace" plugin to overwrite former images.

What about image SEO?

I'm worried about image theft. What should I do?
Y'all could try to disable right-click and drag-and-drop saving of images on your site (like the fantabulous "WP Content Copy Protection" WordPress plugin), merely there's still no 100% safe way.
Hackers can still become access to your original-sized photos from your site'southward source code or past taking screenshots on your site.
While yous tin't preclude this completely, you lot can try to limit the dimensions of your site's images so that their possible usage is limited: smaller images can't exist used for loftier-res graphics, can't be printed at decent sizes, and can't be resold on stock photography sites.
Here are some strategies for mitigating the take a chance of prototype theft:
- Set a smaller maximum dimension for your images. But upload images at 1200 pixels (on the longest side) instead of 1500-2000px.
- No more than increasing prototype sizes for retina screens (even though they won't look as sharp)
- Shrink JPG images to a lower quality. Again, the goal is to limit the image usage possibilities for the "thieves".
- Watermark your images to farther forbid people from re-using them.
Keep in mind that these are all compromises: y'all're increasing protection at the expense of visual impact. High-quality unwatermarked big images will always take a bigger "wow" gene.
Is it enough to only optimize images on the homepage? Or do I need to piece of work on my entire site?
Optimizing your homepage speed is a start, just it is non plenty.
Google doesn't rank your unabridged website based on your homepage alone.
And neither practice users. They might have a good experience on your homepage, but if then they navigate to a very slow page, they however leave your site.
Does using a slideshow bear on site speed?
Yes, information technology can. Unless the slideshow is properly coded, has optimized images, and uses lazy loading, slideshows can negatively affect user feel and SEO.
Read this detailed commodity for what you can replace homepage slideshows with: Homepage slideshows are dead – 4 better means to design the top of your website front folio
What are the file naming conversions for different image sizes?
Not talking about SEO filename conversions (using keywords in the image file names, like "alaska-northern-lights.jpg), but well-nigh how to proper noun unlike sizes of the same image file.
This only applies when you lot manually generate images at different sizes, unremarkably not needed for a WordPress site (which automatically generates "thumbnail", "medium" and "large" versions of your photos afterwards upload).
Hither are some possible options for different-size variations when you showtime with a file called "alaska-northern-lights.jpg":
- Choice i: Dash + size name
- alaska-northern-lights-pocket-size.jpg
- alaska-northern-lights-medium.jpg
- alaska-northern-lights-large.jpg
- Option two: Dash + size in pixels
- alaska-northern-lights-300px.jpg
- alaska-northern-lights-800px.jpg
- alaska-northern-lights-1500px.jpg
- Pick 3: DASH + @ symbol + size modifier
- alaska-northern-lights.jpg (original)
- alaska-northern-lights@0.5x.jpg (half smaller version)
- alaska-northern-lights@2x.jpg (double version for retina screens)
There's no meaningful SEO difference between them, so choose the naming convention you prefer, to be able to reference and use the files on your site quickly.
Why is my website tedious?
I can't perchance answer this here, without reviewing your website first. It's quite a irksome and detailed process, information technology requires a lot of testing and excavation through your site admin expanse and source code. That's why I charge for such piece of work: Website performance optimization service
What I tried doing with this commodity is give you the knowledge to endeavor to test things yourself, and to make you sympathise what all of the page speed opportunities hateful.
What are some common misconceptions about website speed?
This has been brilliantly covered in this Google Search Central video:
Pro tips for developers
A few advanced image optimization guidelines for web experts:
- for smaller site graphics, consider using vector images (SVG with GZIP compression) instead of JPG and PNG
- or better yet, use CSS furnishings wherever possible: filters and blending modes, borders, and outlines, shadows, rounded corners, gradients, unproblematic animations, etc.
- and apply spider web fonts (as opposed to overlaying text in images)
- CDN usage can further better load speeds, but exist mindful of the SEO implications of serving images from a unlike domain.
- WebP image delivery is slowly condign the norm, so make sure the site automatically generates and sends WebP image versions to uniform browsers
- Lazy loading images is a must (meet the "4. b) Defer offscreen images" department to a higher place)
- you lot could also explore image processing & commitment services like ImgIx, Cloudinary, Sirv, ImageKit, ImageBoss, Gumlet: they do a lot of the heavy-lifting, especially useful if the site needs a lot of image manipulations (automatic resizing, cropping, watermarking, etc.)
- and, of class, testing, testing, testing
Still looking for more than geeky info?
- Start past reading Google's "Prototype optimization" article as part of their Web Fundamentals guides, and then their other "Automating paradigm optimization" guide.

Conclusion
Every bit mentioned in the first, these image optimization standards don't really apply to photograph archiving services like PhotoShelter or SmugMug (which have congenital-in security measures, and which generate low-res thumbnails from your original loftier-res files, as needed by the site), or whenever you sell those images equally downloads or prints.
Only if you lot have a cocky-hosted site and only demand to showcase your images on the web, following these image optimization best-practices is a must.
So take some fourth dimension this week to:
- update your image exporting & uploading workflow (run across parts one and 2)
- get back and optimize your site's existing images (see part 3)
