Description
G3, or Group 3, is a highly efficient file format primarily used for compressing and encoding black-and-white images, often in fax communications. It utilizes run-length and Huffman encoding to reduce file size while maintaining quality, making it ideal for transmitting documents over telephone lines. G3 files are widely supported in digital fax servers and document management systems.
