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?

jxl is love. jxl is life (also afaik re-encoding jpeg to jxl is lossless)

Don’t compress your images to 70% jpg!!!
HDD space is essentially free, just get more. With a 70% quality jpg, you lose the ability to crop, edit or blow up your images. It basically limits you to looking at them on a screen. And even there, you’ll get jarring artifacts in dark areas.I think they were saying that they could save space by converting their existing jpg files to avif or jpgXL,
not converting to a 70% quality jpg. JpgXL can do this losslessly so there’s no drawback there, but converting to avif would be a lossy to lossy transcode.EDIT: I completely missed OP’s last paragraph, which does say they are considering converting their existing jpg files into 70% jpgs.

I don’t understand what you mean! 🧐
If I have a 70% quality jpeg, I can open it in Gimp and crop, edit or blow up (a bit) the image.
You can, but 70% quality has visible jpeg artifacts and any editing makes them worse.
Oh. I see!
Thank you 😊
I would really like an android gallery allowing for “full size” favourites with one click. All others get compressed.
I some time had 10GB images in total. Jpeg is already awesome.
No idea why the browsers just dont support it
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.
I always shoot in raw+jpeg with the jpeg quality set to 100%. The raw files have a higher dynamic range and there is little or no processing done to them. The files are large, but storage space is cheap these days. The jpeg files are for convenience and if I don’t like the way they come out, I can process the raw file however I want and export it to whatever format is most suitable for what I’m using it for.
