How to add a signature to a PDF

Signing PDF files may seem daunting, especially if you haven’t done it before. First it’s important to understand the difference between electronic signatures and digital signatures. This article discusses the electronic signature, the equivalent of your handwritten signature. You could think of electronic signature as a image of your signature overlaid on a PDF document.

On other hand a digital signature is characterized by a unique feature that is in digital form like fingerprint that is embedded in a document. The signer is required to have a digital certificate so that he or she can be linked to the document. Digital signature is often authorized by certification authorities that are responsible for providing digital certificates that can be compared to licenses or passports.

Since an electronic signature is what most people expect when they send you a document to sign, in this article we’ll focus on that process only.
