Scanned the wrong way? Phone-camera PDF came out sideways? Rotate PDF Pages turns any page the right way up and gives you back a clean, downloadable file. It is built for the everyday annoyance of a document where one page — or every page — is rotated 90 or 180 degrees from where it should be, and you just want it fixed without paying for desktop software or uploading a private file to a stranger’s server.
You can rotate every page at once, rotate only the odd or even pages (the classic fix for double-sided scans where alternate sheets feed in upside down), or click a single thumbnail to nudge just that one page a quarter-turn clockwise. Live previews redraw the moment you make a change, so what you see is exactly what you will download.
How it works
When you open a file, the tool renders each page to a small thumbnail directly in your browser and reads the page’s current rotation flag. Choosing a rotation marks the relevant pages and updates their previews instantly — no page is re-rendered or re-compressed, so text stays selectable and images keep full resolution.
On download, the tool walks the pages you changed and writes a new rotation value into the PDF: it takes each page’s existing rotation and adds your chosen quarter-turn, wrapping cleanly through 360 degrees. A page already at 90 degrees that you turn another 90 ends up at a correct 180 rather than being reset to zero. The rebuilt PDF is then handed straight to your browser’s download. Because everything happens client-side with WebAssembly, your document never leaves the device — ideal for contracts, payslips, medical letters and anything else you would not want to hand to an upload box.
Example
Say you scanned a 6-page double-sided report and pages 2, 4 and 6 (the back sides) came out upside down. Load the file, set the rotation to 180 (flip), and press Even pages only. Pages 2, 4 and 6 flip in the preview while the odd pages stay put. If page 1 also came in sideways, click its thumbnail once to add a 90-degree clockwise turn. Hit Download rotated PDF and you get a corrected file — same text, same image quality, just facing the right way.
| Situation | What to do |
|---|---|
| Whole document is sideways | Choose 90 clockwise, then “Apply to all pages” |
| Document scanned upside down | Choose 180, then “Apply to all pages” |
| Back sides of a duplex scan inverted | Choose 180, then “Even pages only” |
| One stray page rotated | Click that thumbnail to nudge it +90 degrees |
