Rotate PDF
Turn sideways or upside-down pages the right way up — every page, or only the ones you name. Free, no signup, nothing uploaded.
Fix a sideways scan without uploading it
A scanner that fed a page the wrong way, or a phone that guessed the orientation wrong, leaves you with a PDF that is unreadable without tilting your head. Rotating it is a one-second job that most online tools ask you to upload a document for. This one uses pdf-lib in your browser. The file never leaves your device.
Rotation is added, not replaced
A PDF page carries its own rotation value, and plenty of pages already have one — that is exactly why they look sideways. This tool adds your turn to whatever the page already had, rather than overwriting it. That sounds like a detail and is not: a tool that sets the rotation absolutely will silently straighten some pages and skew others in the same document, which is far more confusing than a page that simply did not turn.
Rotate everything, or only some pages
Leave the pages field empty and every page turns. Fill it in — 1-3, 5 — and only those pages move, which is what a mixed-orientation scan actually needs. Pages outside the document are ignored rather than treated as an error. The rotation is stored as page metadata rather than by re-drawing anything, so no quality is lost and text stays selectable.
