Turn the pages of a PDF and save the result, so the correct orientation stays with the file instead of being something each reader has to fix. Rotation in ninety degree steps handles the two common cases: a page fed into the scanner sideways, and a document that arrives entirely upside down.
Most readers rotate the view only and discard it when the file closes. This tool writes the orientation into the document, so it opens correctly everywhere afterwards.
This tool turns the whole document. To rotate individual pages - the usual case where two sheets in a scan went in sideways - use the PDF Multi Tool and rotate those thumbnails.
No. Rotation records an orientation on the page rather than redrawing the content, so nothing is re-encoded and no quality is lost.
