Rotate PDF

With no page picked, Rotate left and Rotate right turn every page. Pick pages on the preview first, and only those turn: a scan with one sideways page needs a single click on it, then Rotate right. Each page also has its own pair of buttons under it.

The preview turns as you click, and a dashed outline marks every page whose new turn isn’t saved yet. Nothing changes in the file until you press Rotate.

Several PDFs can be turned at once: with nothing picked, each one’s pages turn together. Each PDF saves as a copy named after it, like report-rotated.pdf.

The rotate button in many PDF viewers only turns the page while you look at it, so the file opens sideways again elsewhere. Here the turn is written into each page of the PDF, so it opens the right way up in every app, on every device, and when it’s printed.

A turn adds to how each page already shows, so what you see on the preview is what you get, even in a PDF whose pages were stored on their side.

Rotating sets each page’s orientation; what is on the page stays exactly as it was. Text stays text you can select and search, and photos and anything else already compressed are kept byte for byte. Page content a PDF stores uncompressed is compressed as it is saved, so such a file even gets smaller: our two-page test PDF of small type and 1,200 coloured squares is 55.5 KB, and 7 KB with both pages turned.

Everything else in the PDF is kept: bookmarks, links, fillable form fields and its title and author. A digital signature no longer checks out afterwards, as after any change to a signed file.

A PDF protected with a password can’t be opened here yet, and one whose owner doesn’t allow changing its pages says so; the others rotate as usual.

Tested with PDFium via @embedpdf/pdfium 2.15.1 on a Mac18,5 (Apple M6) on macOS 27.0.1, 2026-10-16. The output was byte-identical in Chromium, Firefox and WebKit.
