Create Your PDF Signature
Use whichever signature style suits you: draw a handwritten signature with your mouse, finger, or stylus; type your name and choose a signature-style font; or upload an image of a signature you already have, ideally a transparent PNG. Each method produces a signature you can resize and reposition on the page.
How to Add a Signature to a PDF
After creating a signature, drag it to the right spot on the page and resize it using any of the handles around its edges and corners. Switch pages using the page controls if your document needs a signature on more than one page, and add a date stamp the same way.
