# PDF forms in C#.NET

PDF fillable forms are digital documents that enable users to input and manipulate data directly within a document. These forms typically contain various fields such as text fields, checkboxes, radio buttons, dropdown menus, and digital signature fields, enabling users to enter information, make selections, and submit forms electronically. PDF forms are commonly used for applications, surveys, registration, and other types of data collection, providing a convenient and efficient way to gather and process information electronically.

## What are forms?

PDF fillable forms are digital documents designed to collect information from users in a structured manner. PDF forms enable users to input data directly into form fields, eliminating the need for manual handwriting or printing.
