Why Use Smush To Optimize Images (The Smush Difference)

Smush was built from the ground up to make it easy for WordPress users to optimize images, activate lazy loading, compress media files, and more – whether they’re just getting started, or a seasoned pro who’s developed thousands of websites.

Improve website performance (along with Google PageSpeed Insights scores) with compressed and optimized images and lazy loading – all while actually delivering a better user experience because the rollout of Core Web Vitals has proven one thing: performance is about far more than just scoring well on performance testing tools. Visitor experience matters.

Next-Gen Formats – Serve Images In WebP or AVIF format

With Smush, you can take advantage of next-gen image formats by converting all of your images to WebP or AVIF. WebP & AVIF are file formats that enable superior image compression and quality retention. All major performance testing solutions, including Google PageSpeed Insights, assess your site’s ability to serve images in these next-gen formats due to the significant impact on visitor experience.

WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPG images. AVIF images are up to 60% smaller than comparable JPG or PNG images.

The best part: Smush’s Next-Gen Formats feature makes this incredibly easy to set up with the ability to host all images locally (not requiring the use of a CDN). Our Next-Gen Formats feature includes automatically replacing PNG and JPEG images on your website’s frontend to serve WebP or AVIF images – with the necessary fallbacks for browsers that don’t support next-gen formats yet.

Note: Yes, Smush supports next-gen conversion for all image formats, including JPEG to WebP/AVIF, and PNG to WebP/AVIF.

With the best image optimization plugin for WordPress – you can finally stop worrying about the performance impact of using the images you want on your website.

Compress Images While Preserving Image Quality

Image compression plugins don’t have to destroy images with a visible, 30% loss in quality. Smush strips hidden information from your images (that can often be bulky), and reduces image file sizes without introducing a visible impact on appearance.

Smush meticulously scans every image you upload – or have already added to your site – cuts all the unnecessary data, and scales it for you before adding it to your media library. And it can serve images in WebP or AVIF format.

Compress Images While You Sleep With Background Image Optimization

Have a large number of images to compress? Smush’s powerful optimization features will continue to work their magic in the background, even when you’ve closed the plugin completely. You’ll receive an email when image optimization has been completed – with a full report.

Compress Any Image in Any Directory

As well as smushing your media uploads, you may want to compress the images stored in other folders. Smush now lets you compress any image in any directory – so that you can optimize all the images on your site – including NextGEN images, images stored on Amazon S3 using WP Offload Media and images in EVERY WordPress plugin and theme package!

Incorrect Image Size Detection

Smush includes a wrong-size image finder. Activate this feature, and your images will be highlighted with smart tips to let you easily resize your images. Quickly locate the images that are keeping you from getting that perfect 100 on your Google PageSpeed test.

Defer Offscreen Images (Lazy Load)

Smush includes built-in lazy loading. If your page has a bunch of images below the fold, lazy loading will drastically speed up your page by serving only the images being viewed, and delaying others further down the page.

Save time with Smush Configs

Configs allow you to save your preferred Smush configuration settings and apply them to your other sites in a few clicks. You can create unlimited configs.
