Rotate PDF: how it works
To rotate a PDF, open the Rotate PDF tool, add your file, turn all or selected pages 90/180/270°, and download. The rotation is saved into the file and everything happens in your browser.
How to use Rotate PDF
- Open the Rotate PDF tool and add your PDF.
- Rotate all pages or pick individual pages to turn.
- Download the rotated PDF.
In your browser vs. uploading to a server
Best for permanently fixing sideways scans so they display upright everywhere, unlike a viewer's temporary rotate that isn't saved.
Frequently asked questions
How do I permanently rotate a PDF page?
- Use the Rotate PDF tool, turn the pages you need, and download; the new orientation is written into the file so it stays rotated in any viewer.
Are my files uploaded to a server?
- No. PDFER runs entirely in your browser using WebAssembly and JavaScript. Your files are read into memory on your device, processed locally, and never sent to PDFER or any third party. Closing the tab or leaving the tool erases them from memory.
