About the PDF Page Rotator
This tool rotates every page in a PDF by 90, 180 or 270 degrees, the fix needed when a document was scanned sideways or upside down. It sets each page's rotation flag directly, the same mechanism every PDF reader and printer already respects, rather than redrawing the page content, and runs entirely in your browser so the file is never uploaded.
How to use the PDF Page Rotator
- 1
Upload the PDF that needs rotating.
- 2
Choose the rotation amount: 90 degrees clockwise, 180 degrees, or 270 degrees clockwise, which is the same as 90 degrees left.
- 3
Check the page count shown to confirm every page was processed.
- 4
Download the rotated PDF.
What people use it for
Fixing a sideways scanned document
Correct a whole document that was fed into a scanner on its side, without needing to reprint or rescan it.
Correcting an upside-down photo scan
Apply a 180 degree rotation to fix a document that was scanned the wrong way up.
Preparing a landscape document for a portrait viewer
Rotate a wide document 90 degrees so it displays correctly in a reader or printer expecting a portrait orientation.
Why rotation doesn't affect file size or text selectability
Every page in a PDF carries a rotation property alongside its actual content, and every compliant reader and printer displays the page according to that property without needing the underlying content to be redrawn. Setting this flag is a tiny, near-instant change compared to rasterising and re-saving a page as a rotated image, which is why the resulting file size barely changes and any selectable, searchable text stays exactly as selectable as it was before.
Why the rotation applies to every page at once
This tool rotates the whole document uniformly, which covers the overwhelmingly common case of an entire document scanned the wrong way. A document where only some pages need rotating, because they were fed into a scanner inconsistently, needs a different approach: split the document into the pages that need rotating and the pages that don't using a PDF splitter, rotate each part separately, then merge them back together.
Tips
- 180 degrees is the fix for a document scanned upside down; 90 or 270 fixes one scanned sideways, and the direction depends on which way it was rotated when scanned.
- If only some pages are sideways, split the document first and rotate just that portion.
- Rotating twice by 180 degrees returns a document to its original orientation, useful if the wrong direction was picked the first time.
