Parallel Zstandard (PZstandard or pzstd) is a multi-threaded implementation of the Zstandard compression algorithm. It is fully compatible with the original Zstandard file format and command-line interface, and can be used as a drop-in replacement.

Compression is distributed over multiple processor cores to improve performance, as is the decompression of data compressed in this manner. Data compressed by other implementations will only be decompressed by two threads: one performing the actual decompression, the other input and output.
