Zstd

Uncommon card · No. 143850

Zstandard is a lossless data compression algorithm developed by Yann Collet at Facebook. Zstd is the corresponding reference implementation in C, released as open-source software on 31 August 2016. The algorithm was published in 2018 as RFC 8478, which also defines an associated media type "application/zstd", filename extension "zst", and HTTP content encoding "zstd". In February 2021, RFC 8878 replaced and obsoleted RFC 8478. RFC 8878 is an Informational publication rather than an Internet Standards Track specification.
