How to rotate a PDF
- Drop your PDF into the box above, or click it to pick a file.
- Choose how far to turn it: 90° right, 90° left or 180° for an upside-down document.
-
Leave All pages selected, or switch to
Selected pages and type the pages that need turning —
for example
2, 5-7. -
Press Rotate PDF and download the result. The file
name gets a
-rotatedsuffix, soscan.pdfbecomesscan-rotated.pdf.
Which rotation do I need?
| What you see | Rotation | Typical cause |
|---|---|---|
| Text runs bottom to top | 90° right | Page fed into the scanner rotated counter-clockwise |
| Text runs top to bottom | 90° left | Page fed into the scanner rotated clockwise |
| Everything is upside down | 180° | Stack loaded the wrong way round in the feeder |
| Only a few sheets are wrong | Any, with a page range | Mixed portrait and landscape originals in one batch |
Why rotate in the browser?
Rotating a PDF is a tiny edit — a single orientation value per page — yet almost every free rotator asks you to upload the whole document to a server, wait, and download it back. Scanned paperwork is exactly the kind of file you least want sitting in someone else’s storage bucket: bank statements, signed agreements, passport copies.
shrink.run makes that edit on your own device. The PDF is parsed by your browser with the open-source pdf-lib library, the new orientation is written in place, and the download link points at a file that never crossed the network. There is no queue, no page limit and no server that could log or keep your document.
Frequently asked questions
Are my PDFs uploaded to a server?
No. The rotation happens entirely in your browser with the open-source pdf-lib library. Your document never leaves your device, which matters when it is a scanned contract, payslip or ID.
Does rotating a PDF reduce its quality?
No. Rotation is a lossless, page-level operation: it changes one number in each page object and leaves the text, images and fonts exactly as they were. Nothing is re-rendered or recompressed, so a rotated page is pixel-for-pixel the original.
Is the rotation permanent, or only how my viewer shows it?
It is permanent. Turning a page with the rotate button in a PDF reader usually only changes the view, and the file opens the old way again on someone else’s screen. This tool writes the new orientation into the downloaded file, so it stays turned everywhere — email attachments, printers and phones included.
Can I rotate only some pages?
Yes. Switch Pages to "Selected pages" and type the page numbers and ranges you want, for example "2, 5-7". Everything outside that list is left untouched, which is the usual case when one scanned sheet went through the feeder the wrong way round.
My scan is already sideways — will rotating make it worse?
No. The tool adds your turn to whatever rotation the page already carries instead of replacing it. A page that was saved at 90° and turned another 90° right ends up at 180°, exactly as you see it on screen. That is why a sideways scan behaves the way you expect rather than jumping back to its original orientation.
How do I fix an upside-down document?
Choose 180° and leave Pages set to "All pages". If only some sheets came out upside down — common when a stack was fed in two batches — rotate those pages by 180° with a page range and download the result.
Does the file size change?
Barely. Only the page orientation entries are rewritten, so the downloaded PDF is within a few kilobytes of the original. If you need a genuinely smaller file, that is a compression job, not a rotation one.
