WP Smushit is the leading image optimization plugin – optimize, resize, and compress images, as well as converting images to WebP format for faster loading web pages.

If your server has already a caching system and you don’t need any plugin for it then Smush is ideal for WordPress users.

In the Smush Dashboard you will see a Bulk smush button which one displays the total attachments to compress, its very easy just click on the button.

Directory Smush: In addition to smushing your media uploads, you may want to smush non WordPress images that are outside of your uploads directory. Get started by adding files and folders you wish to optimize.

Lazy Load: This is not necessary on sites running POPCORN, we already have integrated the lazy loading in theme core.
