- Scenario
- Applying a signature to a PDF document and wanting a specific handwriting style or adjusting the appearance of a digital certificate.

Determine whether you are using a standard "Fill & Sign" tool or applying a secure, certificate-based digital signature, as the font customization capabilities differ significantly between the two methods.
Change the Font Using the Fill & Sign Tool
This is the recommended method for standard electronic signatures where you want a personalized handwriting style.
Open your PDF document and click on the Fill & Sign or Signature tool located in the top toolbar.
If you already have a saved signature, delete it or select the option to add a new signature.
Select the 'Type' option on the signature creation panel to enter your name using your keyboard.
Click on the font style dropdown (often labeled 'Change Style') below the text box and select your preferred handwriting-style font from the available options.
Click 'Apply' or 'Save', then click anywhere on your PDF document to place the newly styled signature.

Modify the Appearance of a Certificate-Based Digital Signature
Certificate-based signatures have restricted font settings for security, but you can alter their overall appearance template.

Frequently Asked Questions
Can I use my own system fonts for an electronic signature in a PDF?
Most PDF editors limit typed signatures to a predefined selection of handwriting-style fonts. This ensures the signature embeds properly and displays correctly on all devices. If you want a completely unique font, you can write your signature on paper, scan it, and import it as an image.
Why can't I change the font on a certificate-based digital signature?
Certificate-based signatures are highly regulated for security and legal compliance. The text generated (such as your name, date, and digital certificate details) uses standardized system fonts to prevent document tampering and ensure readability across different PDF viewers.
How do I change the color of my electronic signature?
When creating or editing a typed signature in the Fill & Sign tool, look for a color palette icon near the font style dropdown. Most PDF editors allow you to select standard colors like black, blue, or red before applying the signature to your document.
