NAME¶
cjxl - compress images to JPEG XL
SYNOPSIS¶
cjxl [options...] input [output.jxl]
DESCRIPTION¶
cjxl compresses an image or animation to the JPEG XL format. It is intended to spare users the trouble of determining a set of optimal parameters for each individual image. Instead, for a given target quality, it should provide consistent visual results across various kinds of images. The defaults have been chosen to be sensible, so that the following commands should give satisfactory results in most cases:
cjxl input.png output.jxl cjxl input.jpg output.jxl cjxl input.gif output.jxl
OPTIONS¶
-h, --help
-v, --verbose
-d distance, --distance=distance
-q quality, --quality=quality
-e effort, --effort=effort
Recognized effort settings, from fastest to slowest, are:
EXAMPLES¶
# Compress a PNG file to a high-quality JPEG XL version. $ cjxl input.png output.jxl # Compress it at a slightly lower quality, appropriate for web use. $ cjxl -d 2 input.png output.jxl # Compress it losslessly. These are equivalent. $ cjxl -d 0 input.png lossless.jxl $ cjxl -q 100 input.png lossless.jxl # Compress a JPEG file losslessly. $ cjxl input.jpeg lossless-jpeg.jxl
