Electronic signature: signing documents effortlessly

You can sign documents on the go with no additional software or devices. Confirming delivery or indicating acceptance of an agreement may be done simply by entering a name or drawing a signature on a smartphone or tablet. Using electronic signatures is also a more sustainable way to save paper. 

Adding a signature to a PDF couldn't be easier: here, we will explain how to do it quickly and securely.


What are the electronic and digital signatures?

Digital signatures are a specific type of electronic signature that uses cryptographic keys to provide a higher level of security and often has a more established legal framework. Electronic signatures, on the other hand, are a broader category that includes various methods of signing documents electronically, with varying levels of security and legal recognition.

Digital signatures are frequently employed in high-stakes transactions, like signing government contracts and financial agreements. On the other hand, electronic signatures are typically utilized for less sensitive documents, such as offer letters, consent forms, and other materials that don't demand the highest level of security.

We will focus on electronic signatures and how to create and use them in PDF Expert.
