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
