PRESERVE IMAGE QUALITY
Some image compression tools destroy images with as much as a 30% loss in quality. Our servers strip hidden bulky information from your images and reduce file size without affecting the 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.
COMPRESS ANY IMAGE IN ANY DIRECTORY
In addition to 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, BUILDERS AND MEDIA LIBRARY PLUGINS
No matter what theme or plugins you use to better 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
Avada Fusion Builder
And many, many, more!
INCORRECT SIZE IMAGE DETECTION
Smush includes a wrong size image finder. Activate and your images will be highlighted with smart tips for scaling your images. Quickly locate the images that are keeping you from getting that perfect 100 on your Google PageSpeed test.
DEFER OFFSCREEN IMAGES
Smush has lazy load built-in. 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.
“I had no idea that my page load time was being dragged down by the images. The plugin nearly halved the time it took.” – karlcw
“I optimise my photos in Photoshop, but Smush makes it so easy – it does it automatically. I can just sit back and enjoy the speed.” – helen432
“Smush helped reduce the total files size on my site and increased browsing speed. Well done guys!” – pdci
“It’s very discrete and does not bother me with an API key or other additional installation steps. The main dashboard of the plugin gives me nice insight. Overall it really fits my needs and I’ll be willing to upgrade to pro if my needs change. I’d recommend it to clients/friends without hesitation. Keep it up!” – tarkan_
WHAT ABOUT MULTISITE?
Smush can be used to optimize all the images across your entire network! Use global settings or configure each site individually.
Smush is super easy to use – no confusing compression software settings. Smush images in your library one at a time or bulk smush up to 50 images at a time. Plus, configure auto-smush to asynchronously scale and compress some or all of your images as they are being uploaded – it’s incredibly fast.
The faster your site loads, the more Google, Bing, Yahoo and other search engines will like it. Your site will load faster and rank higher.

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.
