A scan that comes out sideways is easy to fix on screen: most PDF viewers have a rotate button. The trouble is that the viewer's rotate button usually changes only your view. Send the file to someone else, or open it again tomorrow, and the page is sideways once more. This tool rotates the pages in the file itself, so the change stays.
It runs in your browser, with no upload and no watermark.
How to rotate a PDF
- Drag the PDF into the box at the top of this page, or click it to choose the file. The pages appear as thumbnails.
- Choose whether to rotate all pages or only selected ones. To fix a few pages, click the thumbnails of those pages.
- Rotate by 90 degrees clockwise, 180 degrees, or 270 degrees (the same as 90 degrees counterclockwise).
- Check the thumbnails. Every page should now read from top to bottom.
- Download the rotated PDF.
Which rotation do you need?
| Rotation | What it does | Typical fix |
|---|---|---|
| 90 degrees | A quarter turn clockwise | Page lies on its left side, with the top of the text pointing left |
| 180 degrees | A half turn | Page is upside down, often from feeding paper into a scanner the wrong way |
| 270 degrees | Three quarter turns clockwise, or one quarter turn counterclockwise | Page lies on its right side, with the top of the text pointing right |
If you pick the wrong direction, rotate the same pages again. Two 90-degree turns equal one 180-degree turn, and four bring a page back to where it started.
What happens when you rotate
A PDF stores an orientation setting for each page. The tool changes that setting and saves it in the file. The content of the page is not redrawn or converted to an image, so text stays selectable and searchable, and images keep their quality. Because the rotation is part of the file, it shows in every PDF reader, in email previews and when printing.
Why pages end up sideways
- Paper fed the wrong way. A sheet placed in a scanner feeder upside down or turned comes out that way in the PDF.
- Landscape originals. Wide spreadsheets, charts and certificates are often scanned on a portrait setting and end up lying on their side.
- Phone orientation. Phone scanning apps decide which way is up from how the phone is held, and a phone held flat over a desk often guesses wrong.
- Mixed exports. Some programs save landscape pages as portrait pages with the content turned, which looks sideways in viewers that do not correct it.
Whatever the cause, the fix is the same: select the affected pages, rotate them and save.
What the tool can and cannot do
- It rotates in steps of 90 degrees. It cannot straighten a scan that is slightly crooked, say by 3 degrees. Scan the page again with the paper square against the glass, or use a scanner app with automatic straightening.
- It rotates whole pages. It cannot turn one image or one table on a page while leaving the rest as it is.
- It keeps page order as it is. To move pages as well as rotate them, use Organize PDF, which does both.
- It cannot open password-protected PDFs.
Tips
- Rotate only the pages that are wrong. In a document with mixed orientation, such as a portrait report with a few landscape tables, select the problem pages rather than rotating everything.
- Decide how landscape pages should be read. A wide table printed on a portrait page is often turned sideways on purpose so it fits. For printing, leave it. For reading on a phone or laptop, rotating it to landscape is easier on the reader.
- Fix before you combine. If you are about to join several scans with Merge PDF, rotate the sideways ones first, so the finished file is right from the start.
- Handle phone scans at the source. Phone scanning apps pick orientation from how you hold the phone. Holding it flat over a page can confuse the sensor, so tilt it slightly toward you before you take the shot.
- Shrink after scanning. Scans are often large. Once the pages are the right way up, Compress PDF can make the file small enough to email.
If a page is not only rotated wrongly but also needs a correction, such as a missing date, open the rotated file in the PDF editor afterward.
Privacy and limits
Rotation happens entirely in your browser. The PDF is read and saved on your own device and never uploaded to a server. Once the page has loaded, the tool keeps working offline. That makes it safe for signed contracts, identity documents and financial paperwork.
It is free with no daily limit, needs no sign-up and adds no watermark. Very large files, in the hundreds of megabytes, depend on your device's memory, so they rotate more reliably on a computer than on a phone.
Password-protected (encrypted) PDFs must be opened with their password in another app first and saved as an unprotected copy, if you have permission. This tool does not remove passwords or restrictions.
