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.

your stance on image compression and/ or avif/jxl? (lemmy.ml)

Do you have a general stance about it?

Once every couple of months I look into the state of both projects and it's slow but steadily progressing.

I am mainly looking into it because of the file compression. My tests showed that I can save up to 70% in disk space for a jpg image without losing too much information for both formats, avif and jxl. It depends on the images but in general it's astonishing and I wonder why I still save jpgs in 100% quality.

But, I could also just save or convert my whole library to 70% jpg compression. Any advice?

Jpg at 70% will lose a significant amount of detail. It is a "lossy" format, you cant judt compress data for nothing.

AVIF is significantly more efficient than jpeg, so it loses less image data for higher compression (smaller file sizes).

JXL supports both lossy and lossless compression, and is supposed to be more efficient yet over AVIF. However it's got proprietary all over it because Google et al. For thst alone I would shy away from JXL and go AVIF.

JXL is not proprietary. It's an open, royalty-free format whose reference implementation is BSD-licensed.
