The Graphics Interchange Format (better known by its acronym GIF /ˈdʒɪf/ JIF or /ˈɡɪf/ GHIF) is a bitmap image format that was developed by US-based software writer Steve Wilhite while working at the bulletin board service (BBS) provider CompuServe on June 15, 1987[1] and has since come into widespread usage on the World Wide Web due to its wide support and portability.
