PunyPNG Image Compressor

Its not a major issue as it used to be when we were all stuck in the dark ages using dial up modems to access the Internet, but image compression is still a factor to consider when designing a fast loading website, and this tool from Gracepoint After Five will help compress your images with minimal (if any) loss of quality.

PunyPNG is a free online compression tool that uses several optimization techniques to reduce the file sizes of your images, analyzing the content of the picture and then calculating the best image format to use (PNG/JPG/GIF), with built in support for dirty transparency resulting in upto 35% more compression.
