A zlib-compatible data compression library rewritten in modern C11 with SIMD/CPU-intrinsic optimizations for deflate and inflate. It serves as a drop-in replacement for stock zlib, offering significantly faster compression on modern CPUs.
Use cases
- speed up gzip/deflate compression in my application
- drop-in replacement for zlib with better performance
- fast inflate/decompression library in C
- compression library using AVX2/NEON intrinsics
- replace zlib without changing my code's API calls
When to choose
- you need zlib API compatibility but want major speed gains on modern x86-64 or ARM CPUs
- you want a maintained, fuzz-tested zlib fork with clean modern C code
- your workload is compression-heavy and CPU-bound
When to avoid
- you need exact byte-for-byte output identical to stock zlib in all cases
- you target very old CPUs without SIMD support where gains are minimal
- you need compression formats beyond zlib/deflate/gzip
