Hi

Could you please consider replacing the current jpeg export code used by Lightroom / Camera raw with jpegli ?

I tested it and it's compression efficiency is much better than the one you currently use, resulting in smaller jpeg files for same quality or better quality files for same size

Thank you

Did you know that jpegli files are decoded almost twice as slowly as regular jpegs?

I would prefer to have a choice between the regular jpeg format and jpegli.

JPEG XL is a new format, whereas JPEGLI use some of the improved algorithms from JPEG XL but it produce 100% standard compliant jpeg files. It would be a win-win situation to use this new jpeg encoder for standard jpeg files.
