How to Place a Handwritten Signature in a PDF File

By Ray Padgett

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.

Things You'll Need

  • Adobe Acrobat
  • Scanner (optional)

Step 1

Save your signature file as an image on your computer. You can either actually write it out by hand and use a scanner to scan it in, or draw it on using a computer program like Paint (included with Windows).

Step 2

Open the PDF document in Adobe Acrobat. This process will not work with Adobe Reader.

Step 3

Select "Create Custom Stamp" from the "Tools" menu.

Step 4

Select your signature image file and click "Open."

Step 5

Click the stamp icon in your toolbar.

Step 6

Select your signature from the drop-down menu of stamps.

Step 7

Click once in the area of the PDF where you would like to place your handwritten signature. It will appear there.
