I don’t want to brag, but Smush is the most popular free image optimization plugin for a reason. It’s the best WordPress image optimizer because it is an all-in-one solution that has lossless image compression, lazy loading, bulk smushing (so you can optimize up to 50 images at once) and more. With over 1+ million active installations, Smush has optimized literally billions of images.

Smush will process PNGs, JPEGS and GIFs on OUR superfast servers, freeing up resources on your server so your site performance will not be affected. And the best part? The free version has no daily, monthly or annual caps so you can optimize to your heart’s content. As long as your images are under 5MB we’ll Smush it.

If you want even more cool features, then Smush Pro, with her lightning fast CDN, convert images to WebP, automatically resize your images, convert PNGs to JPEGs, compress images in other directories or in your Amazon S3 cloud and more.

Plus, Smush and Smush Pro integrate well with other popular image plugins such as NextGEN Gallery, WP Offload S3 and WP Retina 2x. Try Smush Pro free for 30 days to see how she can take your site performance to new levels.
