Permanent PDF rotation versus viewer rotation

Why this happens

A viewer can rotate your display without changing the saved PDF. A recipient may therefore still see the old orientation.

What to try first

Download the rotated document and reopen that new file. If only some pages need rotation, check the available selection before applying a document-wide setting.

Try it on a fresh copy

1. Open the PDF and check which way the page needs to turn.
2. Choose the appropriate rotation and process the document.
3. Download and reopen the new PDF. This checks the saved orientation, not just a temporary rotation in your viewer.

How to tell whether it worked

Open the result in a PDF viewer and check its orientation without relying on the viewer’s temporary rotate button.
