Projects / LZHAM


LZHAM is a general purpose lossless data compression library that borrows many ideas from LZMA, but purposely makes several key tradeoffs that favor decompression speed over compression ratio. LZHAM's compression ratio is typically within .5% of LZMA, but decompresses 2-3 times faster. LZHAM's compressor is heavily threaded in a way that does not sacrifice compression ratio. The decompressor supports streaming and memory to memory decompression, and is designed to be particularly fast on embedded devices, handhelds, and game console platforms.

    Release Notes: This release is now capable of fully deterministic compression: given the same input and settings, its output will be the same across platforms, compilers, and optimization settings. Non-deterministic compression is also supported for more scalability.
