How it works
Pick the angle, leave the pages field blank to rotate everything, or list the pages concerned. The rotation is written into the PDF: every reader and printer will honour it, unlike a viewer's temporary rotation.
FAQ
Does rotating reduce quality?
No. Only the page orientation changes; the content is untouched.
How do I rotate a single page?
Enter its number in the pages field, or use the Organise tool to work page by page visually.
Is 90° clockwise?
Yes, 90° turns clockwise; 270° equals 90° the other way.
