Zstandard (or Zstd) is a lossless data compression algorithm developed by Yann Collet at Facebook. The name also refers to the reference implementation in C. Version 1 of implementation was released as Free software on 31 August 2016.[1][2]

Features

Zstandard was designed to give compression comparable to that of DEFLATE (.ZIP, gzip) with higher compression / decompression speeds.

Zstandard combines use of a dictionary-type algorithm (LZ77) and Finite State Entropy (tANS) stage of entropy coding.

License

The reference implementation is licensed under the BSD License, published at GitHub. Since version 1.0, it has additional Grant of Patent Rights.[3]
