# lzip > Lzip is a lossless data compressor with a user interface similar to `gzip` or `bzip2`. > Lzip uses a simplified form of the "Lempel-Ziv-Markovchain-Algorithm"z (LZMA) stream format and provides a 3 factor integrity checking to maximize interoperability and optimize safety. > More information: . - Archive a file, replacing it with with a compressed version: `lzip {{path/to/file}}` - Archive a file, keeping the input file: `lzip -k {{path/to/file}}` - Archive a file with the best compression (level=9): `lzip -k {{path/to/file}} --best` - Archive a file at the fastest speed (level=0): `lzip -k {{path/to/file}} --fast` - Test the integrity of compressed file: `lzip --test {{path/to/archive.lz}}` - Decompress a file, replacing it with the original uncompressed version: `lzip -d {{path/to/archive.lz}}` - Decompress a file, keeping the archive: `lzip -d -k {{path/to/archive.lz}}` - List files which are in an archive and show compression stats: `lzip --list {{path/to/archive.lz}}`
