If you're transcoding why wont you go to avif or another one? If jpeg -> jpeg-xl uniquely better?

JPEG is a lossy format. JPEG -> AVIF adds a second loss operation. JPEG to JPEG-XL is lossless but with a smaller file size. So one does not further degrade the jpegs beyond what they were already degraded in creating them in the first place.

It's a lossless conversion while still saving spaces. You can even convert back to get the exact same file bit-perfect
