How To Electronically Sign Your PDF Documents?

How To Electronically Sign Your PDF Documents in Windows & MacOS?

Are you tired of printing out documents and having to scan them back just to add your signature? There are many ways to sign them electronically. In this guide, we show you how to sign your documents virtually (without the inconvenience of printing, signing, and scanning) before sending. This is a great shortcut, especially when you have a number of documents to sign - save time by electronically signing! Firstly, be aware that there are two completely different signatures: electronic and digital. An electronic signature is a broad category, which includes just a simple image of your signature, whereas a digital signature is far more sophisticated and secure. A digital signature is your identity, which is cryptographically attached to a document and cannot be forged. Do not confuse these two, since this article is about electronic signatures, which are more for personal use.

Signing documents on Windows

You can download it from the official Adobe website. To start signing your documents, open your PDF file and click on the “Fill & Sign” icon on the right hand side. You may need to scroll down a little to find this icon.

Adobe Reader will ask you to type your name. You can choose this option as a signature, but this is probably not the best way, since Adobe Reader will just convert your typed name into a signature. Nevertheless, try it first, as it might fit your needs. The “Image” option allows you to upload a scanned signature image and import it to Adobe Reader as your signature. You can also use the “Draw” option. Click the “Draw” icon.
