I noticed that changing the compression level for JPEG XL format doesn't do anything - it seems stuck at a value of 7.
- changed value is not preserved between program runs
- for different compression values resulted image is always identical and conversion time is always identical, while settings this options to values lower than 7 should significantly speed up the process.
So something is apparanty not working as it should.
Thx

Re: Compression setting for JPEG XL doesn't work.
Thanks to your detailed description I can reproduce the problem.
Which file do you use?- for different compression values resulted image is always identical and conversion time is always identical, while settings this options to values lower than 7 should significantly speed up the process.

Re: Compression setting for JPEG XL doesn't work.
It doesn't depend on file.
For example, with this file https://upload.wikimedia.org/wikipedia/ ... -large.png
I got with XnConvert 1.94:
- quality 80, compression 7 = the size of jxl file of 957671 bytes, conversion time 10s
- quality 80, compression 2 = the size of jxl file of 957671 bytes, conversion time 10s
When using cjxl v0.6.1:
- cjxl -q 80 -e 7 = the size of jxl file of 952609 bytes, conversion time 10s
- cjxl -q 80 -e 2 = the size of jxl file of 1117931bytes, conversion time 3s
