Rotate pages in a PDF online

A PDF scanned sideways, a page fed upside down into the scanner tray, a document received with some pages in landscape while the rest are portrait: rotating pages is a simple-looking operation that keeps coming up whenever you handle digitised paper documents. This tool lets you fix each page's orientation individually or the whole document's in a single operation, entirely in your browser.

How rotation works in a PDF file

Every page in a PDF document carries an orientation attribute (0°, 90°, 180°, or 270°) that tells readers how to display it, independently of the raw content stored in the file. Rotating a page therefore doesn't mean physically flipping the text and images that make it up, but changing this attribute — a very lightweight operation that barely affects the file's size or content quality, unlike what a rotation by image recomposition would do.

Individual or bulk rotation

The tool shows a grid of thumbnails where each page has its own rotation buttons (90° one way, 90° the other), usable independently page by page. For an entire document scanned the wrong way, a group selection lets you apply the same rotation to every page in a single operation rather than handling them one by one. Both approaches can be combined on the same document: group rotation for most pages, then individual adjustment for the exceptions.

Why rotation alone isn't always enough

If your document mixes correctly oriented pages with others that each need a different rotation, the organize tool (reorder/delete/rotate) offers the same rotation feature in an interface that also lets you reorder or remove pages in a single pass — handy if you need to clean up the whole document anyway rather than just fix its orientation.

Frequently asked questions

Can I rotate only some pages and not others?
Yes: select the pages you want in the grid before applying a rotation, or rotate each page individually with its own rotation button.
What's the difference between rotating 90° and 270°?
90° rotates clockwise, 270° counter-clockwise (which gives the same result as three 90° clockwise rotations). 180° flips the page upside down — useful for a document scanned in reverse.
Does rotation change the file size?
No, or negligibly: rotation only changes an orientation attribute attached to each page, with no recompression or redrawing of its content. The file's size stays practically identical.
Why do some PDFs display rotated only in certain readers?
Some older PDF readers, or some viewers built into a browser, ignore the rotation attribute and display the page in its raw orientation. If a recipient reports an orientation problem, this tool rewrites the orientation directly in a standard way, recognised by nearly every modern reader (Adobe Acrobat, macOS Preview, Chrome, Edge).
Can I rotate a PDF scanned upside down in one go?
Yes: if every page is in the same wrong orientation, select them all (or deselect none) and apply a 180° rotation in a single operation, rather than page by page.
Does the rotated file replace the original?
No: a new file is generated on download, leaving the original document unchanged on your device.
