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 deter-
     mined  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
