How is the tilt measured?
Each page is drawn small on your device and we find the angle that lines up the rows of text best. Pages with no clear text lines are left as they are.

Questions
Does deskewing blur the text?
No. The page is turned as a whole and stays vector, so text stays sharp and selectable. Tilts above 5° are left alone.
