Draw, type, or upload a signature and place it on any page. Free and private.
Use this tool free →NilPDF Sign lets you create a signature by drawing it, typing your name in a handwriting-style font, or uploading an image, then place it anywhere on any page of your PDF. Drag to reposition, drag the corner handle to resize, and use the duplicate button to reuse the same signature on other spots or pages. The result is a flattened PDF with the signature image permanently part of the page. This is a visual electronic signature, not a certificate-based digital signature, and NilPDF makes no guarantee that it meets the legal requirements for signing any particular document.

Not unless you choose to. There is an optional "remember this signature on this device" setting that saves it in your browser's local storage for reuse. It is off by default and you can remove a saved signature at any time.
