Description Rafael Linux User 2024-02-11 13:02:32 UTC 
SUMMARY
I’m recoding my TIFF files to JXL with Digikam. I want to do the same with my JPG files, however, before doing it, I have a question, related to re-encoding.

cjxl command line tool from libjxl let users to losslessly transcode JPEG images into JPEG XL. Transcoding preserves the already-lossy compression data from the original JPEG image without any quality loss caused by re-encoding, while making the file size smaller than the original, so my question is what library is using Digikam to transcode JPG to JXL?

Thank you

Currently we load the image and save it as JXL. I would never convert my JPG files to JXL.
