Common Usage

XZ provides excellent compression ratios using the LZMA2 algorithm, often outperforming gzip and bzip2. It is the default compression for many Linux distribution packages (Arch Linux, Fedora), kernel tarballs, and situations where maximum compression is desired.

HTML

<!-- Link or embed with explicit type -->
<link rel="stylesheet" href="file.xz" type="application/x-xz">
