Want to open (or export to) .jxl files? Here’s how to enable the image format support in Ubuntu and Debian.

JPEG-XL (.jxl) is a royalty-free raster-graphics image format supports both lossy and lossless compression. It includes features such as animation, alpha channels, layers, thumbnails, and has better compression efficiency (60% improvement) comparing to JPEG.
