WebTwo examples of commonly used file formats that use LZW compression are the GIF image format served from websites and the TIFF image format. LZW compression is also suitable for compressing text files, and is the algorithm in the compress Unix file compression utility. This algorithm has two steps: Encoding/Compressing … WebLZW is an archive format that utilizes power of LZW compression algorithm. LZW compression algorithm is a dictionary-based loseless algorithm. It's an old algorithm suitable for beginner to practice. Internal algorithm processes byte data. So it's applicable to any file types, besides text file.
