Zstandard compression

Zstandard is a general-purpose lossless compression algorithm.

Zstandard, or zstd as short version, is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by Huff0 and FSE library. It often offers better compression ratios than {{glossary("Brotli_compression", "brotli")}} at equivalent CPU costs, or better CPU costs at equivalent compression ratios.
