How to rotate a PDF
- Drop a PDF into the box above (one file, max 100 MB).
- Choose a rotation: 90° (clockwise quarter turn), 180° (upside down), or 270° (counter-clockwise quarter turn).
- Choose All pages for a uniform rotation, or Specific pages and enter a page list like
1, 3, 5-9. - Click Rotate PDF. The rotated file downloads instantly.
What "rotation" means in a PDF
PDFs store a rotation flag per page rather than rewriting the page contents. That means rotation is lossless — viewers, printers, and other PDF tools all respect the flag. This tool adds your rotation on top of any existing one (so applying 90° twice results in 180°), which matches what most users intuitively expect.
Privacy
The PDF is read into memory in your browser tab, modified with pdf-lib, and offered as a download. No upload, no signup, no server.
FAQ
Does rotating change the file size? Barely — the rotation flag is just a single integer per page.
Can I rotate by an arbitrary angle, like 45°? No. The PDF spec only allows multiples of 90° as a page rotation flag.
Why isn't a page rotating in my viewer? Some viewers cache the rendered page. Try closing and reopening the file, or open it in a different viewer.
