What is a fillable PDF?

Our Ducks in a Row downloadable document is formatted as a fillable PDF. A fillable PDF (also called an interactive PDF or PDF form) is a PDF document that allows people to type directly into the fields, check boxes, select options, and sometimes even save or submit their responses electronically.

Here’s what makes a PDF fillable:

Key Features

• Text fields where users can type information (e.g., names, dates, addresses).
• Checkboxes and radio buttons for selecting options.
• Drop-down menus for choosing from preset lists.
• Signature fields for e-signatures (optional, depending on the setup).
• Auto-save or ability to save a completed version for future updates.

Why organizations use fillable PDFs

• Easy for people to complete at home on their computer or tablet.
• Clean and legible results—no handwriting to interpret.
• Professional appearance with consistent formatting.
• Simple to update and share electronically.

Examples you’d recognize

• Government forms
• Applications or intake forms
• CMS's Ducks in a Row digital version—members type in their information and update it anytime

How they differ from regular PDFs
​A standard PDF is essentially a picture of a document—great for viewing, not for typing into.
A fillable PDF is more like a form—it's designed for interaction.
