PunyPNG is a PNG compression and image optimization tool developed by Gracepoint Berkeley. This is probably the best free online PNG optimization tool.
Another image optimizer but this one is from Yahoo. 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.
