Turn
The turn is added to however the page already sits, so a sideways scan comes upright with one quarter turn — and turning twice turns it twice. Everything else about the file is left as it was: this rewrites your PDF rather than rebuilding it, so bookmarks, links and form fields all survive. It runs in your browser; nothing is uploaded.
