How to Sign a PDF Document — Simplifying the Process With Valuable Tools

What are the steps for signing a PDF document within different operating systems and how can leveraging tools help learners simplify the process?

How To Sign PDF Documents?

In the past, adding your signature to an official document involved printing out the document, signing and scanning it, and emailing it back to the intended recipient. Luckily, evolving technology has brought about a much simpler and faster way to do this. 

With the use of digital tools on the rise, we’re taking a closer look at how you can leverage advanced solutions, like the PDF Reader from Kdan Mobile, to streamline the PDF document signing processes moving forward. 

The Growing Use of Electronic Signatures

Technological advancements and the COVID-19 pandemic quickly led to a significant surge in the use of electronic signatures — with in-person interactions in decline and work-from-home opportunities on the rise. According to Prescient & Strategic Intelligence, this accelerated growth is expected to continue, with the global e-signature market projected to reach a nearly 26.6% compound annual growth rate (CAGR) from 2021 to 2030. 

The difference between an electronic signature and a digital signature

It’s common to assume the terms digital signature and electronic signature are synonymous, but this isn’t the case. Understanding that these solutions aren’t interchangeable, it’s equally important to recognize what makes them distinct. 

A digital signature is a kind of electronic signature that is more secure and tamper-proof — to encrypt and protect PDF documents. This type of signature often requires a digital certificate to be associated with the document, which plays a primary role in identity verification. The cryptographic nature of a digital signature helps key parties:

  • Verify the authenticity of a document and its source.
  • Confirm the identity of the signer.
  • Guarantee no changes were made to the signed document.

An electronic signature, or eSignature, on the other hand, is typically more similar to a digitized handwritten signature verified with the signer’s identity. eSignatures encompass a much wider range of definitions and forms than digital signatures — including any electronic symbol, process, or sound associated with a record or contract that the interested party intends to sign. With an electronic signature, the signer is ultimately indicating their intention to accept a contract or agreement’s terms and conditions, making it considerably easier to use but of less value.
