About the G3 format
G3 — CCITT Group 3 FAX
G3 is a monochrome image format defined by the CCITT (ITU-T) standard for Group 3 fax transmission. It encodes pages as compressed bitstreams using Modified Huffman (MH) or Modified READ (MR) compression, designed to minimize transmission time over telephone lines.
Common uses
- Fax machine page storage and archiving
- Converting legacy fax images to PDF or TIFF
- Legal and medical document fax archives
- Telephone-transmitted document recovery
About the XZ format
XZ — XZ Compressed File
XZ is a single-file compression format using the LZMA2 algorithm, which provides some of the best compression ratios available for general-purpose single-file compression. It is the default format for many Linux distribution packages and kernel releases. While compression is slow, decompression is surprisingly fast, making it ideal for distributable archives.
Common uses
- Linux kernel and software release compression
- Arch Linux package format (.pkg.tar.xz)
- Maximum compression of source code and text
- Firmware and embedded image distribution
