Website speed is a critical user-experience and SEO factor affecting bounce rates and rankings , and image sizes often are the overwhelming performance bottleneck. People expect websites to be really fast. Google does too. Website performance has become an essential SEO and user-experience factor in recent years, as connection speeds have greatly improved.

Otherwise, your hard-earned traffic decreases, and your Google rankings eventually drop too. Follow this guide for detailed instructions on how to fix those performance issues. So if you care about your site performance and, in turn, its SEO , you 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.

But how should you resize and compress your photos before uploading them to your site? How can you automate this process? And what file formats should you use? It all starts with finding out the right image dimensions needed for your pages, to help you better prepare them on your computer first. 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 take a lot more time to upload and are slower to optimize. These services need the highest image size you have to allow printing at larger sizes and good-enough quality.

Also, these platforms prevent image theft by automatically resizing images to a smaller size when displayed on the web. On the web, DPI is irrelevant and only pixel dimensions matter! For example, slideshow images are usually wider; blog images are medium-sized at a width equal to the page width minus the sidebar ; thumbnails are smaller, etc. Here are instructions for finding the element selector in other browsers. For example, full-page slideshows that are popular on wedding photography sites keep the original aspect ratio of images.

So for any images that span the entire width of the browser, images should be pixels in width , and any height you prefer depending on whether you want to keep the original aspect ratio of your photos or go for a more panoramic crop.

This is not a scenario where we need to double the image dimensions for retina screens, because that would create huge px images with large file sizes as well, not to mention the risks of image theft. Thumbnail galleries are special scenarios where you ignore the size of your thumbnails, and instead, make sure images are large enough when enlarged. Since those images will open up in a full-screen view, I recommend sizing them to at least pixels on the longest edge , so they look large enough on desktop and tablets.

Restricting the image dimensions like this will keep the file size reasonably small, 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 :. Choosing a quality WordPress theme can do all this for you.

Using the methods described above, you can determine the actual width of the content area by measuring any paragraph of text, for example:. Alternatively, you could use a browser extension like View Image Info properties to get that same info:.

Armed with that knowledge pixels in this example , you can now double that size to take into account retina screens so pixels in width here. Depending on your specific site theme, and your image theft risk-tolerance :- , you can lower that number down to a more reasonable pixels on the longest edge so px in width for horizontal images, or px in height for vertical ones, maintaining their original aspect ratio of course.

Which leads us to the second most important aspect…. Choosing something like 60 or 70 gives you good-enough quality for much smaller file sizes sometimes you can see a reduction in file size without any perceived quality loss.

But between and , the quality difference is unnoticeable, while the difference in image file size is enormous. Most photographers will know that images with gradients pose a big problem here walls, skies, background colors. And always save JPG images in the sRGB color profile, which is what most browsers understand, to avoid any image color integrity issues. 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 contain areas of solid color created by you in Photoshop or other tools online could be better saved in other lossless file formats with absolutely no perceived visual differences.

Simple image format decision tree source. Without relying on a pixel-grid, SVG files have the great benefit of being infinitely scalable without any loss in quality. You have to test this out yourself, on a per-image basis. But like I said, this only holds true for graphics with solid colors.

Whenever you try this same experiment with a regular photo taken with your camera , JPG usually wins by a lot. Even if you correctly set the right pixel dimensions and compression levels when exporting your images using Photoshop or Lightroom, for example , the following tools can take image optimization to the next level. Lightroom are already down to their lowest acceptable compression visually, I found using plugin reduces file size but also reduces the noticeable visual quality.

But even when going for a lossless compression type, where the results are pixel-identical to your original images, these tools can reduce file sizes as much as 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.

Image optimization is both an art and a science: an art because there is no one definitive answer for how to best compress an individual image, and a science because there are well-developed techniques and algorithms that can help significantly reduce the size of an image. There are a bunch of great plugins that do a lot of work for you, automatically. They take every image you upload and then compress it to optimize the file size.

A free account with them gives you a decent monthly quota, and you can get a premium plan to allow optimizing many more images per month if you need to. You can also pay a one-time fee to get a bunch image optimization credits useful when using their bulk optimizer to go through your existing Media Library. In this case, make sure you properly configure the plugin settings to only choose the thumbnail sizes that matter to your site.

Otherwise, those one-time set of credits will go by really fast. Then regenerate all past thumbnails , and then, finally, do a bulk optimization of your entire Media Library. Alternatively, a nifty little tool that can quickly analyze and compress your already-published photos is Image Optimization Tool by WebsiteToolTester , the process is quite simple:. Click to download the optimized images as a ZIP archive that you can replace the old images with.

Before diving into image-specific testing tools, know that you can gain a lot of insights from these two popular website speed testing tools: Google PageSpeed Insights and GTmetrix. The page intentionally does a lot of things wrong in order to highlight its problems in testing tools:. The Google PageSpeed Insights report outlines some important performance opportunities that you might encounter on your own site:. While the browser is responsible for resizing the image 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 as large as needed by your page layout see part 1 of this guide. Loading all the other ones lower down the image can be delayed until other critical site resources have finished loading. Fixing this issue is relatively simple. Just use an image optimization plugin that supports the lazy loading feature:. 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 you can do is use a plugin that can generate WebP images and then automatically deliver them to compatible browsers:. Google determined that your image file sizes could be smaller, even with a pixel-perfect lossless compression. That means that your current images are not optimized to the max. You can see that GTmetrix identified the right size at which those images were being displayed on the page. Make sure your photos are correctly sized based on your page usage see part 1 of this article.

Alternatively, you can use this great new performance tool: Page Weight by imgIX. Beyond those guidelines, here are 3 different strategies for optimizing website images, depending on your level of involvement:. WordPress users, install either ShortPixel or Imagify , and configure it to:. Depending on the number of images in your Media Library, you can get a one-time plan to handle all your images in one go. For other platforms SquareSpace, Wix, etc.

When compressing images on your computer first, you can double-check if the quality level is good enough with a small file size, but without any visible noise or JPG artifacts. After making changes, be sure to regenerate all thumbnails again.

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 image. If used as a thumbnail, a smaller-sized JPG is generated. But… people can still get access to the high-res images if they know how to tweak the URLs of those images.

So for image protection purposes, only upload compressed images at the pixel dimensions needed by your page layout up to a maximum of pixels on the longest edge. Images are just one factor when it comes to website performance. Other issues might be affecting your page load speeds:. After exporting images on your computer, make sure they look well there before uploading them to the site. Because browsers do a sloppy pixel interpolation job because they prioritize speed over quality.

In practice, the portion of the filesize taken up by metadata is quite small with larger images, but it can make a big difference, proportionally, for smaller images. The 8. Deleting old images from your Media Library is risky because any references or links pointing to them might get broken. This guide is only focused on website images.
