The Graphics Interchange Format, better known by its acronym GIF (/dʒɪf/ JIF or /ɡɪf/ GHIF), is a bitmap image format that was developed by a team at the bulletin board service (BBS) provider CompuServe led by American computer scientist Steve Wilhite on June 15, 1987. It has since come into widespread usage on the World Wide Web due to its wide support and portability.
