About:
LZFSE is a compression library and command-line tool developed by Apple, designed for high-performance energy efficiency. It offers a superior balance between compression ratio and speed, outperforming zlib in decompression speed while using less energy. The tool is ideal for iOS and macOS applications where CPU and battery usage are critical considerations.

Key Features:

High-performance decompression with low CPU overhead
Superior energy efficiency compared to other algorithms
Optimized for Apple hardware and iOS/macOS ecosystems
Includes both library and CLI tool for easy integration

Use Cases:

Compressing assets for iOS and macOS applications to reduce app size
Processing large datasets on mobile devices with minimal battery impact
Network transmission compression where decompression speed is prioritized

Alternatives:

zlib – LZFSE provides faster decompression and better energy efficiency, though zlib has wider cross-platform support
zstd – Similar performance goals, but zstd offers more tuning options while LZFSE is Apple-optimized
