This is a web-based tool I found while reading comments on a SmashingMagazine article about clever tricks to optimizing PNG images. It's really useful if you don't want to spend lots of time optimizing several images.

Quote:Smush.it uses optimization techniques specific to image format to remove unnecessary bytes from image files. It is a "lossless" tool, which means it optimizes the images without changing their look or visual quality. After Smush.it runs on a web page it reports how many bytes would be saved by optimizing the page's images and provides a downloadable zip file with the minimized image files.
