Graphic Interchange Format. An efficient method of compressing image files without loss of data or distorting the image. (GIF compression is therefore lossless.) The algorithm only works for files with 256 or less colours and is best at compressing images with large areas of homogeneous colour. It is not so efficient for images with many colours and complex structures.

GIF files are normally given a .gif file extension. For file format information see links for .gif.
