Rotate a PDF 90° Clockwise

About this option

A quarter turn to the right is what most scanned or phone-photographed documents need: a landscape scan of a portrait page is lying on its left side, and turning it 90° clockwise stands it upright. This page opens the PDF rotator already set to 90° clockwise, so you only drop the file in.

When to use it

  • A scanner fed pages sideways and the text reads from bottom to top
  • A phone-camera PDF came out turned to the left
  • Only a few landscape pages in a portrait document need straightening

How to use it

  1. 1Drop your PDF — the preview already shows each page turned 90° to the right
  2. 2Leave the page range empty to turn every page, or type something like 2-4, 7
  3. 3Check the thumbnails and click Rotate
  4. 4Download the new PDF

Frequently asked questions

Which way is 90° clockwise?

The top of the page moves to the right. A page lying on its left side ends up upright.

Can I rotate only some pages?

Yes. Enter a page range such as 1-3, 8 and only those pages turn; the rest are left untouched.

Does rotating change the text or quality?

No. Only the page's rotation flag changes, so text stays selectable and images keep their original quality.
