Rotate PDF
Rotate pages in a PDF to fix sideways or upside-down scans.
Fix the orientation of all pages or just specific ones in a PDF. Choose to rotate by 90°, 180°, or 270° clockwise. Uses pdf-lib to set rotation flags directly in the file without re-rendering - instant results regardless of file size. Perfect for correcting scans taken in the wrong orientation or standardising a mixed-orientation document.

How to use Rotate PDF
Two steps, and nothing to install.
Drop your PDF and choose an angle
Pick 90°, 180° or 270°, and either apply it to every page or specify just the pages that came out wrong.
Download the corrected file
The rotation is written into the document and the corrected PDF is offered for download immediately.

How this works in your browser
Every PDF page carries a rotation entry, a value of 0, 90, 180 or 270 that tells a viewer how to orient the page when displaying it. This tool uses pdf-lib to read that entry and write a new value, and that is genuinely all it does. No page is rendered, no content stream is rewritten and no image is re-encoded, which is why the operation is instant regardless of document size and why there is no quality cost whatsoever. It also explains the difference from rotating inside a PDF reader: that usually adjusts your view only, while this changes the stored property so every future reader honours it.

Common ways to use Rotate PDF
Fixing sideways scans
Correct pages that came out of a scanner or phone camera rotated the wrong way.
Standardising a mixed document
Bring a file that mixes portrait and landscape pages into a consistent orientation before sharing or printing.
Preparing a document for print
Make sure every page prints the right way up rather than relying on the recipient to rotate it themselves.
Frequently asked questions
What it can and cannot do, and what happens to your files.
Can I rotate individual pages rather than the whole document?
Yes. Specify which pages to rotate, or apply rotation to all pages at once. Both options are available.
Does rotating re-render the page content?
No. pdf-lib updates rotation metadata only - page content is not re-rendered, so there is no quality loss and processing is nearly instant.
Can I rotate in both clockwise and counter-clockwise directions?
Yes. 90° rotates clockwise, 270° effectively rotates counter-clockwise. 180° flips the page upside down.
Why is rotating instant even on a huge file?
Because almost nothing is being rewritten. Rotation is stored as a single property on each page telling viewers how to display it, so the tool changes that number rather than touching any page content. A 500-page scan rotates as quickly as a one-page memo.
My PDF viewer rotated the page but it saved back sideways. Why?
Most viewers rotate only your on-screen view and do not write the change into the file. This tool sets the rotation in the document itself, so the correction travels with the file to whoever opens it next.
Does rotating affect the text or make the file bigger?
No to both. Since no content is re-rendered, text stays selectable, images keep their resolution, and the file size is effectively unchanged.
Is my file uploaded anywhere?
No. The rotation property is updated inside your browser tab and the file is re-saved locally.
