About zstd
zstd is a compression algorithm designed to provide high compression ratios. Compression reduces the size of data for storage or transfer, and a high ratio means the compressed representation can be substantially smaller than the original. The product information does not specify speed, memory use, compression levels, supported file formats, or whether it refers to a library or standalone command-line program. Those details should be checked for a particular workflow. Its documented purpose is data compression, with the stated emphasis on achieving high compression ratios rather than any particular interface or deployment model. The compression ratio is its stated design emphasis.
