Rotate PDF
The Rotate PDF tool turns every page of your document by 90°, 180° or 270° and hands back a new file to download. It is ideal when a scanner or camera saved pages sideways or upside down. The entire conversion runs right in your browser — the PDF is never uploaded and never leaves your device.
How rotating a PDF works
Every page in a PDF carries its own rotation attribute (0°, 90°, 180° or 270°) that tells the viewer how to turn the page when displaying it. This tool does not re-render the page content or change its data — it only adjusts that rotation angle in the page metadata. That makes rotation fast, lossless, and harmless to the quality of text and images.
The tool uses the PDF-lib library, which runs as JavaScript in your browser. The input is a single PDF file; the output is a new PDF with every page turned by the chosen angle. The chosen angle is added to any existing rotation on the page — so if a page was already rotated 90° and you add another 90°, the result is 180°.
How to use Rotate PDF
- Click the file selector and choose a PDF from your device.
- In the dropdown pick the angle: 90° clockwise, 180°, or 270° (90° counter-clockwise).
- Click the Rotate and download button.
- The browser processes the file and automatically offers a new document,
otoceno.pdf, to download.
Example of how angles add up on a page that already has a rotation:
| Existing page rotation | Chosen angle | Resulting rotation |
|---|---|---|
| 0° | 90° clockwise | 90° |
| 90° | 270° (counter-clockwise) | 0° (straightened) |
| 180° | 180° | 0° |
What Rotate PDF is good for
It most often helps with scanned documents saved sideways or upside down, with invoices and contracts photographed on a phone, or with PDFs assembled from differently oriented pages. Clerks, accountants, students, and anyone who wants to straighten a document before printing or sending will find it useful.
Because everything happens locally in your browser, the tool is also suitable for sensitive documents — contracts, payslips, medical records. The file is not uploaded to any server, so no third party can access it. Tip: if pages are each rotated differently, rotate the document once and open the result to check; you can repeat with a different angle, since rotation is non-destructive and can always be undone by rotating again.
FAQ
Is my PDF uploaded to any server?
No. All processing happens directly in your browser using JavaScript. The file never leaves your device and is not sent anywhere.
Does it rotate all pages or just one?
The tool rotates every page of the document by the same angle at once. Rotating only selected pages is not yet supported.
Does rotating reduce the document quality?
No. The tool only changes the rotation value in the page metadata; it does not re-render the content. Text and images keep their original quality and the file stays practically the same size.
What is the difference between 90° and 270°?
90° turns the page to the right (clockwise), 270° to the left (counter-clockwise). 180° flips the page upside down.
Can I undo a rotation?
Yes. Rotation is non-destructive — just rotate the result back by the complementary angle (for example, after 90° clockwise rotate by 270°) to return to the original orientation.
Does it work on large or password-protected PDFs?
Large files are handled, though processing may take a moment depending on your device. Encrypted, password-protected PDFs may fail to open — remove the password first.
Why does a page look different than I expected after rotating?
The chosen angle is added to the page's existing rotation. If the page was already turned, the result is the sum of both angles (modulo 360°).
Do I need an account or installation?
No. The tool is free, needs no registration, and runs right in the browser on desktop and mobile.
