How to use the rotate pdf
- Drop a PDF onto the drop zone or click to choose one.
- Tap pages to select them, or select none to work on every page.
- Use Left 90°, Right 90° or 180°, or the rotate buttons under each page. Thumbnails update to show the result.
- Click Save rotated PDF and download it.
Worked example
Fixing a sideways scan
If page 1 is already set to 90° and you press Right 90° for it, it is saved at 180°. Rotation is relative to the page's current rotation, so pressing Right 90° four times brings a page back to where it started.
How it works
Rotation is stored in each page's /Rotate setting (a multiple of 90 degrees) with pdf-lib. The new angle is the current angle plus your change, modulo 360. Page content is not re-rendered or re-compressed.
Assumptions
- Rotations are clockwise and relative to each page's existing rotation.
Frequently asked questions
Are my files uploaded?
No. Your PDF is processed in your browser on your own device and is never sent to our server. You can disconnect from the internet after the page loads and the tool still works.
Does rotating reduce quality?
No. Only the page's rotation setting changes. Text and images are untouched.
Can I rotate by 45 degrees?
No. PDF page rotation supports multiples of 90 degrees only.
Can I use a password protected PDF?
Not for editing. Encrypted or permission-restricted PDFs are refused, because editing them without decrypting would create a broken file or bypass restrictions set by the author. If you are allowed to, remove the protection in the software that created it first.
Limitations
- Files up to 100 MB are accepted, but very large or complex PDFs depend on your device memory and can be slow on phones.
- Only 90 degree steps are possible.
- Encrypted or permission-restricted PDFs cannot be edited.
