StripFile
Do you have a web site? Then speed it up with Stripfile, a simple tool which cuts GIF, JPEG, PNG and HTML files down to size (gains can range from a few bytes to 50% or more). The program removes the redundant information these files often contain, helping your pages load more quickly and reducing bandwidth requirements. Integrates with Explorer, too -- just right-click on a selected file or folder, then click 'Strip' to begin compression...
