Key takeaways
- Rotating in a PDF viewer often doesn't save — Rotate PDF changes the file itself.
- Rotate all pages at once or only the selected ones.
- Use Left/Right for 90° turns; two clicks fix upside-down pages.
- New scans are auto-rotated when text runs sideways.
A landscape table that appears sideways, a scanned page that's upside down, a mix of portrait and landscape pages — rotated pages make documents hard to read. Many viewers let you rotate the view but forget it as soon as you close the file. Here's how to fix the orientation permanently.
How to rotate PDF pages
- Open Rotate PDF and add your file.
- Pages appear as thumbnails.
- To rotate everything, use the Left or Right buttons for all pages.
- To rotate some pages, select them first, then rotate.
- Download the corrected PDF.
Left rotates 90° counter-clockwise, Right 90° clockwise, and Reset returns a page to its original orientation.
Rotate while you organize
If you also need to reorder or delete pages, use Organize PDF — it lets you rotate, move and remove pages in one view. See reorder PDF pages.
Scanned documents rotate automatically
When you scan with Scan to PDF, Osd-Scan detects text running sideways or upside down and rotates the page for you. If it gets one wrong, tap the rotate icon on that page before saving.
Landscape pages in a portrait document
Wide tables and charts are often landscape on purpose. Rotate them so the text reads correctly when the reader turns the device — usually 90° to the left, so the top of the table faces the binding side.
On your phone
Rotate PDF works in the mobile browser and in the Osd-Scan app. Tap pages to select them, tap rotate, and save.
Private and lossless
The rotation is written into the PDF without re-compressing anything, and the file never leaves your device.
Frequently asked questions
Why does my PDF go back to sideways after I rotate it in the viewer?
Many viewers only rotate the view, not the file. Rotate PDF saves the new orientation into the document.
Can I rotate only one page?
Yes. Select just the pages you want and rotate them.
Does rotating reduce quality?
No. Pages keep their original content; only the orientation changes.
How do I rotate a scan before saving it?
In Scan to PDF, tap the rotate icon on the page card.
