Rotate a PDF 90° Counterclockwise

About this option

When a page lies on its right side, a quarter turn to the left puts it upright — the same as rotating 270° clockwise. This preset opens the rotator on that setting, which is the usual fix for landscape tables and slides that were exported turned the wrong way.

When to use it

  • A wide table or slide was exported lying on its right side
  • A photographed page needs its top moved from the right edge to the top
  • You rotated 90° clockwise and the page went the wrong way

How to use it

  1. 1Drop the PDF — the preview turns each page 90° to the left
  2. 2Pick a page range if only part of the document is affected
  3. 3Click Rotate once the thumbnails look right
  4. 4Download the result

Frequently asked questions

Is counterclockwise the same as 270° clockwise?

Yes. A quarter turn to the left and three quarter turns to the right end in the same position.

Can I rotate the same file again?

Yes. Load the new PDF and rotate again; each pass adds to the page's current orientation.

Does it work on password-protected PDFs?

Not directly. Remove the password first with the Unlock PDF tool, then rotate.
