NAME
       djxl - decompress JPEG XL images

SYNOPSIS
       djxl [options...] input.jxl [output]

DESCRIPTION
       djxl decompresses a JPEG XL image or animation. The output format is
       determined by the extension of the output file, which can be .png,
       .jpg, .ppm, .pfm. If the JPEG XL input file contains an animation,
       multiple output files will be produced, with names of the form
       "output-framenumber.ext".

OPTIONS
       -h, --help
           Displays the options that djxl supports.

       -j, --pixels_to_jpeg
           By default, if the input JPEG XL contains a recompressed JPEG file,
           djxl reconstructs the exact original JPEG file if the output file
           has the .jpg (or .jpeg) filename extension. This flag causes the
           decoder to instead decode the image to pixels and encode a new
           (lossy) JPEG in this case.

       -q quality, --jpeg_quality=quality
           When decoding to .jpg, use this output quality. This option
           implicitly enables the --pixels_to_jpeg option.

EXAMPLES
           # Decompress a JPEG XL file to PNG
           $ djxl input.jxl output.png

           # Reconstruct a losslessly-recompressed JPEG file
           $ djxl lossless-jpeg.jxl reconstructed.jpeg
