Hi Hert,

The rotation itself is not lossy, but everytime you save a JPG you will lose quality. I recommend only saving to JPG after manipulations are done. As far as I know, the compress factor is only used when saving. Once an image is saved, it is then loaded "as is", independent of the original compression factor.

Best regards,
