XnView Software

Hello,
when using the "save as" to save a guetzli-compressed jpg, I can choose quality between 0 and 100 as well as "progressive" jpg. However, Guetzli does not support that. Whats going on here and why is it possible without getting an error message that guetzli needs quality setting >= 84?
Thanks,
Jens

yes right, currently guetzli use same options dialog as jpeg

But this should not work. However, if I chose quality below 84 and "progressive", I get an exported jpg anyway. Whats going on? Is guetzli bypassed in thess cases?
