How to add digital signatures to PDF documents

You’ll need to follow some general steps before you can sign documents digitally.

First, you’ll need a digital certificate, either from a registered provider or through a self-sign service.

You cannot add a digital signature to a PDF file without a certificate.

You’ll also need access to an app that allows you to add digital signatures to your documents. Simple tools like Windows Microsoft Word or Adobe Reader can achieve this.

Alternatively, you might want to opt for a more feature-rich solution that offers advanced document management capabilities.

It’s usually possible to configure the software, such as by setting a visual signature to display at the bottom of a document whenever you sign (along with your digital signature), so you should familiarize yourself with all the options and set your preferences.
