1. Can you extract a signature from a PDF?

Yes, you can, but the difficulty of doing so depends on the type of signature you want to extract from the PDF. There are two types of signatures: digital and image (electronic) signatures. A digital signature contains a verified ID of an organization or a person, including name, serial number, email address, and expiration date. The digital signature has two keys (certificates): a public key used to lock or encrypt data and a private key used to unlock or decrypt the encrypted data.

An image signature is inserted from a saved image captured from a camera or created from a trackpad. It's very easy to extract an image signature from one PDF file to another PDF or Excel, PowerPoint, Word, etc. Whether you want to extract a digital signature or an image signature from a PDF, read further to learn how to do it.
