Practical use cases

  • A scanner fed a few pages in landscape by mistake, mixed into an otherwise portrait document.
  • A photo taken sideways and turned into a PDF, where the page needs a quarter-turn to read normally.
  • An entire scanned document that came out upside down from a duplex scanner — rotating with nothing selected fixes every page at once.

How the rotation is saved

Rotate writes the new orientation directly into each page's own rotation value inside the PDF — the same property every PDF viewer reads to decide how to display a page. That means the change survives opening the file anywhere, not just in PDFDistrict; it isn't a display trick limited to this site. Rotating the same page more than once in a session adds each turn to what's already there, so 90° twice becomes 180° — useful if you picked the wrong angle and want to correct it without starting over. Selecting specific pages rotates only those; leaving none selected rotates the whole document by the same angle.

Common problems

  • Only some pages rotated: check whether any thumbnails were selected — with a selection, only those pages turn; only an empty selection rotates everything.
  • The page rotated the wrong way: apply the rotation again in the direction needed — since rotations add up, a second 90° turn corrects a page that only needed 180° in total.
  • The file won't load: a password-protected or corrupted PDF shows "This file is password protected" or "This file appears to be corrupted or is not a valid PDF" before any rotation can happen.
