Rotate PDF

What this tool does

Rotate PDF fixes sideways and upside-down pages. Rotate each page with its own buttons or select several and turn them together, preview the result on thumbnails, and save a corrected copy that keeps the original quality.

Document feeders and phone scanning apps frequently produce pages that are sideways or upside down, especially when a stack mixes portrait letters with landscape spreadsheets. Reading such a file means tilting your head or rotating the view every few pages, and many viewers do not save that view rotation.

Every PDF page has a /Rotate setting that tells viewers how to display it. This tool changes that setting with pdf-lib, adding the rotation you choose to whatever the page already had. Nothing is re-rendered, so text, images and file size stay essentially the same. Thumbnails are drawn locally with pdf.js and update instantly as you rotate.

How to use Rotate PDF

1. Drop a PDF onto the upload area to see a thumbnail of every page.
2. Use the rotate buttons under any thumbnail to turn that page left or right by 90 degrees.
3. To rotate several pages at once, click them (shift-click selects a run) or type a range in the side panel, then press 90° left, 90° right or 180°.
4. With nothing selected, the panel buttons rotate all pages.
5. Check the +90° style badges, which show the extra rotation on each page.
6. Press Apply rotation and download the corrected PDF.

Tips for better results

• Use the Odd or Even selection buttons to fix duplex scans where every back side came out upside down.
• Rotations add up: two 90° right clicks equal 180°, and four bring the page back to normal.
• Reset all rotations clears your changes without reloading the file.

Common use cases

• Correcting landscape tables in a scanned report so they read upright.
• Fixing every second page of a double-sided scan that was fed the wrong way.
• Turning a sideways photographed receipt before submitting an expense claim.
• Preparing a presentation exported in portrait so slides display in landscape.

Common mistakes to avoid

• Rotating pages in a viewer and expecting the change to be saved; most viewers only rotate the on-screen view.
• Selecting pages and then rotating with the per-page buttons, which affect only that one page, not the selection.
• Trying to rotate encrypted PDFs, which must have their protection removed first.
