    Squoosh CLI

    Squoosh CLI is an experimental way to run all the codecs you know from the Squoosh web app on your command line using WebAssembly. The Squoosh CLI uses a worker pool to parallelize processing images. This way you can apply the same codec to many images at once.

    Squoosh CLI is currently not the fastest image compression tool in town and doesn’t aim to be. It is, however, fast enough to compress many images sufficiently quick at once.

    Installation

    The Squoosh CLI can be used straight from the command line without installing using npx:

    $ npx @squoosh/cli <options...>
    

    Of course, you can also install the Squoosh CLI:

    $ npm i -g @squoosh/cli
    $ squoosh-cli <options...>
    

    Usage

    Usage: squoosh-cli [options] <files...>
    
    Options:
      -V, --version                                          output the version number
      -d, --output-dir <dir>                                 Output directory (default: ".")
      -s, --suffix <suffix>                                  Append suffix to output files (default: "")
      --max-optimizer-rounds <rounds>                        Maximum number of compressions to use for auto optimizations (default: "6")
      --optimizer-butteraugli-target <butteraugli distance>  Target Butteraugli distance for auto optimizer (default: "1.4")
      --resize [config]                                      Resize the image before compressing
      --quant [config]                                       Reduce the number of colors used (aka. paletting)
      --rotate [config]                                      Rotate image
      --mozjpeg [config]                                     Use MozJPEG to generate a .jpg file with the given configuration
      --webp [config]                                        Use WebP to generate a .webp file with the given configuration
      --avif [config]                                        Use AVIF to generate a .avif file with the given configuration
      --jxl [config]                                         Use JPEG-XL to generate a .jxl file with the given configuration
      --wp2 [config]                                         Use WebP2 to generate a .wp2 file with the given configuration
      --oxipng [config]                                      Use OxiPNG to generate a .png file with the given configuration
      -h, --help                                             display help for command
    

    The default values for each config option can be found in the codecs.ts file under defaultEncoderOptions. Every unspecified value will use the default value specified here. Better documentation is needed here.

    Auto optimizer

    Squoosh CLI has an experimental auto optimizer that compresses an image as much as possible, trying to hit a specific Butteraugli target value. The higher the Butteraugli target value, the more artifacts can be introduced.

    You can make use of the auto optimizer by using “auto” as the config object.
