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.
Discover the features that set Smush apart from other image optimization plugins:
Lossless compression (Basic Smush) – Strip unused data and compress images without affecting image quality.
Lossy compression (Super Smush) – Optimize images up to 2x more than lossless compression with our cutting-edge, multi-pass lossy image compression.
Ultra Smush (Pro Only) – Take performance to the next level with 5x image compressing power! Your images will be as light and fast as possible, while still preserving remarkable image quality.
Built-In Lazy Loading – Lazy load images to defer loading of offscreen images with the flip of a switch.
Convert to WebP or AVIF (Pro Only) – Use the Next-Gen Formats feature to convert and automatically serve images in next-gen WebP or AVIF format.
Bulk Smush – Bulk optimize and compress images with one click.
Background Optimization (Pro Only) – Smush’s powerful image optimization features will continue to run in the background even when the plugin is closed.
Resize Images – Set a max width and height, and large images will scale down as they are being optimized.
123-point global CDN (Pro Only) – Ensure blazing-fast image delivery anywhere in the world. Includes automatic WebP/AVIF conversion and image resizing, plus, GIF / Rest API support.
Incorrect Image Size Detection – Quickly locate images that are slowing down your site.
Directory Smush – Optimize images even if they aren’t in the default WordPress media library.
Automated Optimization – Asynchronously auto-smush your attachments for super fast compression on upload.
No Monthly Limits – Optimize all of your images (up to 5 MB in size) free forever (no daily, monthly, or annual limits).
Gutenberg Block Integration – View image compression information directly in image blocks.
Multisite Compatible – Flexible global and subsite settings for multisite installations.
Optimize All Image Files – Smush supports optimization for all of your PNG and JPEG files.
No Performance Impact On Your Server – Image optimization is not run on your website’s server to prevent wasting server resources (that you pay for) and is instead run using the fast, reliable WPMU DEV Smush API.
Configs – Set your preferred Smush settings, save them as a config, and instantly upload to any other site.
And many, many, more!

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. More information can be found in this Google developers article and this web.dev article.
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!
Compatible with Your Favorite Themes, Page Builders, and Media Library Plugins
No matter what theme or plugins you use to manage your WordPress media library, Smush has you covered. Check out just a few of the popular products Smush is working with to help make your site faster and more efficient:
WP All Import
WP Offload Media
WP Media Folder
WP Retina 2x
NextGen Gallery
WPML
Envira Gallery
Avada Fusion Builder
And many, many more!
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.

Privacy
Smush does not interact with end users on your website. The only input option Smush has is to a newsletter subscription for site admins only.
Smush uses a third-party email service (Mailchimp) to send informational emails (opt-in) to the site administrator. The administrator’s email address is sent to Mailchimp and a cookie is set by the service. Only administrator information is collected by Mailchimp.
Smush sends images to the WPMU DEV servers to optimize them for web use. This includes the transfer of EXIF data. The EXIF data will either be stripped or returned as it is. It is not stored on the WPMU DEV servers.
