Rotate PDF

Rotate PDF pages 90° left or right and save the new orientation for good — perfect for sideways scans or upside-down pages. DocLab runs entirely in your browser, so your file is never uploaded and there's no account, no watermark, and no page or size limits.

Rotate PDF — how it works

Open your PDF. Drop in or pick the PDF and DocLab shows a thumbnail grid of every page so you can spot which ones are turned the wrong way.
Turn the pages you need. Click a page (or select several) and hit Rotate left or Rotate right; each click spins it 90°, so two clicks flips an upside-down page a full 180°.
Check the preview. Watch each thumbnail update live until every page sits upright, then keep rotating any stragglers until the whole document reads correctly.
Download the fixed PDF. Export and your browser saves a new PDF with the rotation baked in — it opens already upright everywhere, no re-rotating on reopen.

Your files never leave your browser

Your PDF stays on your device from start to finish. DocLab opens, rotates, and re-saves the file using code that runs inside your own browser tab, so the bytes are never sent to a server and there is nothing to upload, queue, or delete afterward. The rotation work happens locally in a background worker, which is also why it stays fast on big scans. Because no server touches your document, you can rotate confidential contracts, medical records, or ID scans privately, and once the page has loaded it keeps working with your Wi-Fi off. The tool is open source, so anyone can verify these claims by reading the code. Read the privacy policy →

Frequently asked questions

Is it safe — does my PDF get uploaded?

No upload happens. Rotation runs locally in your browser, so the file never leaves your computer and isn’t stored on any server.

Is it free, and do I need an account?

Yes, it's completely free with no account, no email, and no watermark added to your rotated PDF.

Are there page or file-size limits?

There are no imposed page or size caps. Very large scans take longer because everything is processed on your own device, but they still work.

Does it work offline, on Mac, or on my phone?

It works in any modern browser on Windows, Mac, Linux, ChromeOS, and mobile, and keeps working offline once the page has finished loading.

Does the rotation actually stick when I reopen the file?

Yes. The chosen angle is written into the saved PDF, so the page opens upright in any viewer instead of reverting to its original sideways orientation.
