Usage

The command line syntax of rzopfli is similar to gzip and zstd, and some options derived from the Zopfli reference implementation. rzopfli preserves input files by default, just like zstd. It’s possible to remove them automatically by using --rm.

Basic usage

Compress a file into the gzip format

rzopfli foo.txt

Write the processed data to standard output

rzopfli -c foo.txt

Remove an input file after successful compression

rzopfli --rm foo.txt

Performs 50 compression iterations

rzopfli -i 50 foo.txt

Compress a file into the zlib format

rzopfli --format zlib foo.txt

Generate shell completion

--generate-completion option generates shell completions to standard output.

The following shells are supported

bash
elvish
fish
nushell
powershell
zsh

Example

rzopfli --generate-completion bash > rzopfli.bash
