You are reviewing a contract and need to circle a clause. You are marking up a student assignment and want to sketch a correction in the margin. You have a blueprint or technical diagram that needs annotations drawn directly on the page. In every case, the question is the same: how do you draw on a PDF without printing it, without buying Adobe Acrobat, and without spending ten minutes figuring out a complicated tool?

To permanently rotate a PDF, you need a tool that saves the rotation into the file itself — not just your viewer. Upload your PDF to Transfonic's free PDF Rotate Page tool, rotate the pages you need, and download the saved file. The rotation is embedded permanently and displays correctly in every PDF viewer.
