How to rotate PDF pages
- Press Choose PDF, or drop a PDF onto the box.
- Pick 90° clockwise, 180° or 90° anticlockwise.
- Keep All pages, or choose Only these pages and type them, such as 2, 4-6.
- Press Rotate PDF, then download the rotated file.
How the PDF rotator works
Every PDF page has a rotation setting that tells viewers which way up to show it. The tool changes that setting in your browser with pdf-lib, adding the angle you choose to each page's current rotation, and saves a new file.
Because only the setting changes, the pages are not re-drawn or compressed: text stays sharp and selectable, and the file size barely changes. The rotation is saved in the file, so it stays fixed when you email or print it. Nothing is uploaded.
The logic
New rotation = (current rotation + chosen angle) mod 360. PDF rotations must be multiples of 90 degrees, so the result is always 0, 90, 180 or 270.
Example
A scanned contract has pages 2 and 3 lying on their side. Choose 90° clockwise, select Only these pages and type 2-3. Those two pages turn upright and pages 1 and 4 stay as they were.
A page that was already set to 270 degrees and is turned 90° clockwise ends up at (270 + 90) mod 360 = 0, its normal position.
Tips and common mistakes
Not sure which way?
Clockwise turns the top of the page to the right. If you get it wrong, rotate the result again by 180 degrees.
Separate pages that need different turns
Run the tool once for each angle, using the output of the first run as the input to the next.
Tidy a whole scan
After fixing rotation you can split out the pages you need or combine several scans into one file.
Shrink scanned files
Scans can be large. If the rotated file is too big to send, compress the PDF.
Frequently asked questions
Is the rotation permanent?
Yes. The new rotation is saved in the downloaded file, so every viewer and printer shows the pages the new way.
Does rotating reduce quality?
No. Only the page's rotation setting changes; the content is not re-drawn or compressed.
Is my file uploaded?
No. Everything happens in your browser and the PDF never leaves your device.
Can I rotate by 45 degrees?
No. The PDF format only allows page rotations in steps of 90 degrees.
