LZW has other more vital uses, chief among them being that it is the default compression algorithim for the Tagged Image File Format (TIFF) file format. Despite the similarity in their names, TIFF is not merely GIF’s smarter handsomer brother. TIFF is the de-facto standard for lossless image storage. WebLZW (Lempel-Ziv-Welch) is a lossless compression algorithm based on LZ78. It was developed by Terry Welch in 1984. It is infamous for being widely used in various standard formats (especially GIF) by developers unaware that it was encumbered by patents. The patents expired around 2003. There are many variations of LZW in use.
