From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This is the first I’m hearing of jpeg-xl what are some of its advantages? I thought everything was moving to av1.

IMO the most important points:

  • JXL allows for progressive rendering (e.g. it can only los an image partially)
  • JXL is faster
  • JXL has better compression on higher quality levels
  • AVIF is better for low fidelity images

JXL was made for images only, whereas AVIF comes from Video frames. Technically JXL is superior in most categories. I can’t tell for the license what is better.

Also: JPEG can be losslessly converted to JXL. Typically converting from one lossy format to another lossy format decreases quality. But in case of JXL, you can take old JPEGs and make them smaller without losing information.

This is one of my favourite comparison of the bunch. Tl;dr JPEG XL is actually made for pictures and not just a still frame of a video and it truly shows. Cloudinary has a lot of great content talking about its advantages for the web: https://cloudinary.com/blog/tag/jpeg-xl

That’s a really informative graph. I just converted a bunch of images from png to jpg. I’ll try to convert to this tomorrow. Im curious about the size difference.

Great to hear and good luck! Another good thing to know is, that you can always convert back and forth between JPEG and JPEG XL without any data loss, I love that functionality!
