GIFCruncher Desktop reduces the size of Web images by as much as 90%.

GIFCruncher can reduce the size and download times of your GIF file by up to 90%, without sacrificing quality. It works by removing redundant and unseen information from single and animated GIFs.

There are two modes of operation.

In 'Auto' mode, GIFCruncher suggests optimization levels and gives you comparison images from which to choose.

In 'Advanced' mode, you have complete control over the optimization process.
