How to fix sideways, upside-down and crooked PDF pages

Updated

Scanned bundles often come out with a few pages sideways, one upside down, a blank page from the back of a sheet, and a mix of A4 and Letter. You can fix them one at a time — or all at once.

One click

  1. Open Fix PDF layout and choose the PDF.
  2. Leave the recommended fixes on: turn pages upright, straighten crooked scans, remove blank pages.
  3. Choose a paper size — Most common keeps the document consistent — and press Fix layout.
  4. Read the list of what changed, then download.

How it decides

Pages are turned by the direction their text runs, so they read correctly rather than just matching their neighbours. Crooked scans are measured from their lines of text and straightened. Blank pages are those with no text and no marks, even if a scanner added a few specks.

Nothing is re-rendered: text stays sharp and selectable, and links and form fields move with the content.
