The Top And Simple Way To Add A PDF Form Signature

In some cases, when you apply for an online job and submit it via e-mail, you have to add signature to pdf files with your CV. This can be done only through printing, signing, and scanning the document and attaching it to your email.. That’s a boring, time consuming job. Besides, there are other ways to add a signature into a PDF file that are simpler and faster. Here you can see the quick ways below:

Differentiate between the electronic and certificate signature (digital signature):

It’s becoming common knowledge that electronic signatures are easy to use.. With one click of the mouse or by using fingerprints, users may easily sign documents. A certificate signature (digital signature), however, is encrypted for security which only allows the authorized user access to use it. 

An electronic signature is equivalent to the original handwritten signature. It is just an image of your signature on a PDF page overlaid. On the other side, a Certificate signature (digital signature) is authenticated, meaning an individual with a private signing key has seen and signed the document. It’s secure, but it is complicated, too. The Certificate signature (digital signature) is the equivalent of a notarization signature online. A reliable, certificate authority third party is the notary of authentication of your identity.
