How to Place a Handwritten Signature in a PDF File

Adobe encourages users worried about security to insert digital signatures into PDF files. These include information like a name, address, and even photo. However, nothing there actually looks like your signature. Inserting a handwritten signature image into a PDF file is, confusingly, an entirely unrelated process. However, once you have the signature on your computer, inserting it into documents is more simple.

The “Stamp” tool lets you place handwritten signatures on digital documents.
