Smush.it offers an API that performs these optimizations (except for stripping JPEG meta data) automatically, and this plugin seamlessly integrates Smush.it with WordPress.

Features

• stripping meta data from JPEGs
• optimizing JPEG compression
• converting certain GIFs to indexed PNGs
• stripping the un-used colours from indexed images

How does it work?

Every image you add to a page or post will be automatically run through Smush.it behind the scenes. You don’t have to do anything different.

Installation and Use

Download the WP Smush.it plugin and extract in your wp-content/plugins directory. Activate the plugin and you’re done.
