2. How to Add Digital Signature to PDF

Now you have learned how to add an electronic signature to PDF from the steps above, let me show you how to add a digital signature to a PDF by using PDFelement. While an electronic signature works as an equivalent of your handwritten signature, a digital signature is the equivalent of a legally binding signature.

By using strong encryption algorithms, a digital signature involves the use of a key pair: a private key and a corresponding public key. The private key is kept securely by the signer, while the public key is freely available to anyone who wants to verify the signature.

Therefore, a digital signature can ensure the identity of the signer, confirm that the document or message originates from them, and detect any modifications or tampering of the signed file.

Taking the authority of your digital signature into consideration, we suggest that you sign PDF documents with a certificate-based digital signature by using PDFelement.

Below we'll cover how to use PDFelement to add digital signatures to PDF files.

Step 1: Open the File and Navigate to Protect Menu

Launch PDFelement and open the PDF document if you want to add a digital signature.

Step 2: Insert Signature in PDF

Under the "Protect" Menu, click on the "Sign Document" button. Move your cursor to the area where you want the signature to be added and click on it. When you do this, a dialogue box titled "Sign Document" will pop up.
