Rotate PDF Pages

Turn sideways scans upright and save the rotation permanently.

Every tool runs entirely in your browser. Your files are never uploaded to a server.

Rotating a PDF changes each page’s stored orientation, so it opens the right way up everywhere instead of only in the viewer you turned it in. Rotate every page or name specific ones. It runs entirely in your browser.

How to use Rotate PDF

  1. Add your PDF. Drag it onto the drop zone or click to browse. Several files can be rotated in one run.
  2. Choose the turn. Ninety degrees either way, or a hundred and eighty for upside-down scans.
  3. Pick the pages. Leave it as "all", or name the ones that came out sideways: 3-5, 9.
  4. Rotate and save. The new PDF opens the right way up in every reader, not just yours.

About rotating PDF pages

Page rotation in PDF is a property, not a transformation. Every page carries a /Rotate entry holding 0, 90, 180 or 270, and readers apply it at display time; the underlying content stream is left exactly as the document was written. That single fact explains most of the confusion around sideways PDFs. When you click the rotate button in a desktop reader, many applications change only how the page is shown to you and never touch the file, which is why the document looks correct on your machine and sideways to everyone you send it to. Others do write the value but only when you explicitly save, so an unsaved rotation vanishes the moment the file is closed. Writing the property properly, as this tool does, means the orientation travels with the document — into other readers, into a printer’s spooler, into the preview thumbnail your email client generates. Because only a number changes, rotation is one of the very few PDF operations that is genuinely lossless and essentially free: no image is resampled, no text is re-laid out, and a hundred-megabyte scan comes back the same size it went in. The common real-world case is a batch scanner that fed some sheets in the wrong way round, leaving a document that is mostly upright with a few pages on their side. Name those pages rather than turning everything, or you will simply move the problem to the other pages.

Frequently asked questions

Why does my PDF look rotated in one app but not another?
Because most viewers let you turn a page on screen without writing anything to the file. That is a view setting, not a change. This tool writes the orientation into the page itself, so it travels with the document to any reader, printer or phone.
Does it add to the rotation already on a page?
Yes, deliberately. A page already stored at 90° turned another 90° becomes 180°, which is what "turn this page" means. It does not reset pages to a fixed angle, so mixed documents stay relatively correct.
Can I rotate only some pages?
Yes. Name them the same way as everywhere else: 3-5, 9, 12-. Scanned documents often have a handful of landscape pages among portrait ones, and this is the case the page selector exists for.
Does rotating reduce quality or increase the file size?
Neither. Rotation writes a single number into each page dictionary. No content is re-encoded, nothing is re-rendered, and the file size barely moves.
Is anything uploaded?
No. The document is read and rewritten on your own device. No request is made while it runs.
