Rotate PDF

Scanned a document sideways, or got a PDF with one landscape table among portrait pages? Rotate the pages you need by 90° either way or turn them upside down. The rotation is stored as the page’s display angle, so nothing is re-encoded: text stays searchable and images keep their full quality. Files are processed in your browser and never uploaded.

How to use this tool

1. Choose one or more PDF files.
2. Pick the rotation: 90° clockwise, 90° counter-clockwise or 180°.
3. Choose which pages turn — all, odd, even, or a list such as 1, 3-5, last.
4. Download the rotated PDF (or all files as a ZIP).

Formula

New angle = (current angle + rotation) mod 360°, where 90° counter-clockwise is the same as 270° clockwise.

PDF pages store their display rotation as 0, 90, 180 or 270 degrees clockwise. Rotating again adds to the existing angle, so a page already at 90° turned another 90° clockwise ends at 180°.

Example

A scanned contract where pages 2 and 4 came out upside down: choose 180°, “Pages listed below” and enter 2, 4. Those two pages go from 0° to (0 + 180) mod 360 = 180° and read correctly; the other pages are unchanged.

Rotating for double-sided scans

When a feeder scans the back sides upside down, rotate only the even pages by 180°. If a whole book was scanned sideways, rotate all pages 90° in the direction that brings the top of the text to the top edge — the result shows exactly what a viewer will display for the first rotated page.
