Form filler

Last updated November 30, 2025

A form filler is a software program that fills forms in a UI. Form fillers can be part of a larger program, like a web browser, a web browser extension, password manager or even an enterprise single sign-on (E-SSO) solution.

Types

Web form fillers

Designed to complete HTML-based forms, such as login fields, shopping checkout pages, or online surveys like Google Forms. These are commonly built into web browsers, browser extensions, or password managers to streamline online data entry.^[1]

PDF form fillers

Specialized software for completing PDF forms. Government agencies, such as the IRS and State Department websites often refer to PDF-based documents simply as “forms.”^[2] Dedicated PDF form fillers can handle interactive fields, digital signatures, and validation requirements for official submissions.
