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
