GIF (Graphics Interchange Format)
.GIF is one of the two most common file formats for graphic images on the World Wide Web. The LZW compression algorithm used in the GIF format is owned by Unisys, and companies that make products that exploit the algorithm (including the GIF format) need to license its use from Unisys.
