How to Add a Signature to a PDF Document

No one likes paperwork today, and therefore PDF comes into existence. And also, the traditional way of adding the signature on the hard copy is minimized. So here we are going to provide a comprehensive guide on how to add a signature to a PDF file.

There are different ways to add a signature to the PDF file. But there is a lot of difference between adding just a signature and placing a verified digital signature. Here we will cover all the aspects so that everything is transparent in your mind. Most smartphones, such as Android and iPhone, offer a feature to add a signature to any document, but these are not verified. For a verified signature, you have to go for paid services.

Verified Signatures are also subdivided into two categories. Electronic signature and Digital signature. There are some differences, so let us check out what they mean.

Electronic Signature

An electronic sign is a Quick sign you add on invoices, documents, and bills. In other words, if you are dealing with general paperwork, then an Electronic signature is sufficient for you.

Digital Signature

Digital sign is more advanced, highly authenticated, and more authorized. This is widely used in a notary or third-party witness where you require a high level of security. When you add a digital signature to your document, then that document is encrypted and locked. For a digital signature, you have to go for the third-party tool.

Where can you add an electronic signature?

The most common question nowadays is whether an electronic signature is legal. The answer is YES! If you create an ID and set a verified digital signature, then this is legal, and only you have the authentication to make changes to that document. Firms widely use it for online contracts.
