How to rotate a sideways PDF and save it
A page that opens sideways should stay upright after you save — not just while you view it.

Many PDF viewers let you rotate a page on screen, but that setting is often just for viewing — reopen the file elsewhere and it’s sideways again. To fix it for good, the rotation has to be written into the document itself, which is exactly what this tool does.
How Pditor does it
Choose 90, 180, or 270 degrees clockwise and apply it to every page or just the ones that are wrong. Pditor updates each page’s rotation and saves it into the PDF, so it opens upright in Acrobat, your browser, your phone, and print — everywhere. Nothing else on the page changes; text and images keep their quality.
Private and free
The tool runs in your browser session and your file auto-deletes within an hour. No watermark, no signup.
Frequently asked questions
- How do I permanently rotate a PDF?
- Open the Rotate PDF tool, pick the angle (90, 180, or 270 degrees) and the pages, and download. The rotation is saved into the file so it stays upright in every reader.
- Why does my PDF look rotated only in some apps?
- If you rotated it in a viewer without saving, the change is display-only. Rotating and downloading here writes the rotation into the document so it's permanent.
- Can I rotate only some pages?
- Yes. Apply the rotation to all pages or enter a range so only the sideways pages are corrected.
- Will rotating reduce quality?
- No. Rotation changes page orientation only; text, images, and resolution are untouched.
