# gzip > Compress/uncompress files with `gzip` compression (LZ77). > More information: . - Compress a file, replacing it with a `gzip` archive: `gzip {{path/to/file}}` - Decompress a file, replacing it with the original uncompressed version: `gzip {{[-d|--decompress]}} {{path/to/file.gz}}` - Compress a file, keeping the original file: `gzip {{[-k|--keep]}} {{path/to/file}}` - Compress a file, specifying the output filename: `gzip {{[-c|--stdout]}} {{path/to/file}} > {{path/to/compressed_file.gz}}` - Decompress a `gzip` archive specifying the output filename: `gzip {{[-c|--stdout]}} {{[-d|--decompress]}} {{path/to/file.gz}} > {{path/to/uncompressed_file}}` - Specify the compression level. 1 is the fastest (low compression), 9 is the slowest (high compression), 6 is the default: `gzip -{{1..9}} {{[-c|--stdout]}} {{path/to/file}} > {{path/to/compressed_file.gz}}` - Display the name and reduction percentage for each file compressed or decompressed: `gzip {{[-v|--verbose]}} {{[-d|--decompress]}} {{path/to/file.gz}}`
