How this works
Rotate is relative, not absolute — turning an already-90°-rotated page another 90° lands it at 180°, not back to 0°. Choose specific pages or all of them, and each selected page's current rotation is added to, not replaced.
Common questions
Can I rotate different pages by different amounts in one pass?
Not in a single operation — one rotation amount applies to whichever pages you select. For different pages needing different rotations, run the tool again on a different page selection.
Does rotating change the page's actual content, or just how it displays?
Just the page's rotation flag (the standard PDF /Rotate property) — the underlying content stream is untouched; every compliant PDF reader honours that flag and displays the page turned, without needing to redraw anything.
