Fix orientation without recreating the document
Choose 90, 180, or 270 degrees and apply the turn to all pages or the page numbers you select. This corrects sideways scans and landscape pages without first converting them to pictures.
A printed page number and the PDF viewer’s page number can differ when a document has a cover. Preview the chosen pages and inspect the downloaded copy before replacing your original.
What rotation does not do
Turning a page does not straighten a crooked scan within the page or shrink the file. Use a scan-cleanup workflow for skewed content and PDF compression when the goal is fewer bytes.
Processing happens locally. Keep the original document, particularly when it includes digital signatures or complex interactive content, because rewriting a PDF may affect those features.
