XnView Software

I have tried that, and checked 'Use estimated quality (when possible)', but then the file is bigger.

I am using format "same as original", so "settings" button is greyed.

Hello, I am trying to use batch convert to rename files using EXIF data. The problem is that the file size reduces (not definition). So I suppose there is quality loss.

I know I could use batch rename for this, but convert is more flexible, because it allows output directory selection.

Thanks for ...
