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.

N. B. In some cases GIFs should be replaced with PNG files. You can control this behaviour on the Options page. It is off by default.

So if you want to optimise the websites main template images it would be worth checking out PunyPNG as well as Smush.it.
