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
