'''Zstandard''', or '''Zstd''', is a general-purpose compression algorithm and file format. It is designed to have a good balance between compression ratio, compression speed, and decompression speed.

== Identifications ==
For at least some versions of Zstd format, files begin with signature bytes {{magic|25 b5 2f fd}}.
