So you’ve received a PDF document by email that you need to sign and return, or you’ve sent one to your client to sign. How do you accomplish that task?
Do you print the PDF, sign the document, scan the document, and then email it? If you do, you are being unnecessarily inefficient. There is an easy way to open and sign that document without ever printing and scanning, and it’s probably already on your computer.
The free Adobe Reader includes multiple ways to get your signature on a document. It will create a signature for you just from text, but if you want your real signature on the document but just can’t navigate turning your signature into a digital image that you can drop into the document, Adobe Reader even lets you hold your signature up to your computer’s webcam.
Go here for a detailed article on how to use Adobe Reader to sign a PDF.
