FastLZ
A fast, portable ANSI C implementation of LZ77 compression optimized for speed over ratio.
What is FastLZ?
FastLZ is a fast, portable implementation of the LZ77 lossless data compression algorithm written in ANSI C. It is designed to compress repetitive data like text or raw pixel data quickly, prioritizing speed over compression ratio. The library is widely used in games, open-source projects, and as a base for other compression tools.
Developers working on performance-critical applications, embedded systems, or projects needing a lightweight, fast compression library with minimal dependencies. It is also suitable for those integrating compression into C/C++ projects or using bindings in other languages.
Developers choose FastLZ for its exceptional speed, portability, and simplicity—it's a single-header library that works across many platforms and architectures. Its focus on fast compression and decompression makes it ideal for real-time data processing where throughput is more important than maximum compression.
