A reference C implementation of the LZFSE compression algorithm, which uses Lempel-Ziv matching with Finite State Entropy coding for fast compression and decompression. It ships as a static library with a simple API plus a command line tool, and is the format used by Apple's Compression framework since OS X 10.11 and iOS 9.

Use cases

  • compress data faster than zlib deflate at similar ratios
  • read or write Apple LZFSE-compressed files
  • decompress assets from iOS or macOS apps
  • embed a lightweight C compression library in a project
  • compress files from the command line with the lzfse tool

When to choose

  • you need fast compression/decompression with ratios comparable to deflate
  • you are interoperating with Apple's Compression framework or LZFSE-formatted data
  • you want a small, dependency-free C library

When to avoid

  • you need maximum compression ratio (use zstd or xz)
  • you need cross-platform ecosystem support, streaming APIs, or many language bindings
  • you need dictionary or multi-threaded compression features
