Rotation changes the stored page orientation so readers, printers, and downstream tools see the page correctly. It is different from temporarily turning the view in a PDF reader.
Identify only the affected pages, rotate them in the correct direction, and reopen the saved file to confirm the change persists.
Permanent rotation creates predictable pages for readers and later processing while preserving intentional portrait and landscape layouts.
Find every incorrect page
Scan thumbnails and pay attention to mixed portrait, landscape, duplex, and mobile-camera pages.
Choose rotation direction
A 90-degree clockwise turn differs from counterclockwise; upside-down pages need 180 degrees.
Apply and save
Rotate only the selected pages and create a new file.
Verify downstream use
Reopen, print-preview, and test OCR or conversion if those steps follow.
