# zstd
> Compress or decompress files with Zstandard compression.
> More information: <https://github.com/facebook/zstd>.
- Compress a file into a new file with the `.zst` suffix:
`zstd {{path/to/file}}`
- Decompress a file:
`zstd -d {{path/to/file}}.zst`
- Decompress to `stdout`:
`zstd -dc {{path/to/file}}.zst`
- Compress a file specifying the compression level, where 1=fastest, 19=slowest and 3=default:
`zstd -{{level}} {{path/to/file}}`
- Unlock higher compression levels (up to 22) using more memory (both for compression and decompression):
`zstd --ultra -{{level}} {{path/to/file}}`
