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
