    Use Cases & Benefits

    • Provides a general-purpose data compression library and command-line tools using the .xz file format with LZMA2 compression.
    • Delivers higher compression ratios than gzip with reasonable decompression speed and supports multithreaded compression.
    • Use for compressing software packages to reduce distribution size while maintaining fast decompression on client machines.
    • Use for embedding efficient compression in C applications requiring a zlib-like API for easy integration.
    • Use for compressing executable files by chaining filters like BCJ with LZMA2 to improve compression ratios.
