Overview ​

The Form (or AcroForm) feature allows users to create interactive form fields in a PDF document, enabling other users to provide information by filling out these fields. Essentially, PDF form fields are a type of PDF annotation known as Widget annotations. They are utilized to implement interactive form elements such as buttons, checkboxes, combo boxes, and more.

As PDF is an electronic format, it provides advantages that traditional paper forms do not have. For instance, users can edit information that has already been entered. Additionally, document creators can distribute PDF forms over the internet, restrict the content and format entered by users, as well as programmatically extract and categorize the information filled in by users.
