WP Smush.it is a plugin for WordPress that optimizes images by using an API from Smush.it. Everytime you add images to a page or post they will automatically run through Smash.it behind the scenes. The existing images can be checked and optimized. You just need to browse the ‘Media Library’ and use the ‘Smush.it now!’ link for any image you would like to smush.
