Scanned a document and it came out sideways? This tool rotates every page of a PDF by 90 degrees so it reads the right way up. Run it again to rotate further. The rotation is saved into the file, so it stays correct wherever you open it.
Why scanned pages land sideways in the first place
Sideways PDFs almost always trace back to how the paper met the scanner. Feed a landscape spreadsheet into a portrait scanner, or drop a stack into an automatic feeder rotated ninety degrees, and every page inherits that twist. Phone scanning apps add their own confusion, guessing orientation from the camera's tilt and sometimes guessing wrong. The content is fine; it is just turned the wrong way.
This tool fixes that by rotating every page 90 degrees per pass and writing the change into the file itself. Because the rotation is baked into the PDF rather than applied only in your viewer, the page reads correctly everywhere it opens, including on phones and in print. Run it twice for an upside-down 180 degree fix. After straightening a freshly split file from split PDF, the page is ready to share.
A clean rotation that preserves your content
Rotating does not re-render or re-compress anything. The page's text stays selectable, its images keep their original resolution, and only the orientation flag changes, so a rotated contract is byte-for-byte as readable as before. That makes rotation a safe, lossless edit you can apply without worrying about degrading quality.
- Permanent fix: the new orientation is saved into the PDF, not just shown in one viewer.
- Repeatable: run it again to reach 180 or 270 degrees.
- Whole-document: every page turns together in one pass.
Once your pages face the right way, assemble them with merge PDF into a finished document, or visit editpdf123 for the rest of the toolkit.
