PDF Forms are digital documents that allow users to fill out information electronically. They are created using the Portable Document Format (PDF), which preserves the layout and design of the original document. Users can enter text, select options, and submit the form without needing to print it out. These forms are commonly used for applications, surveys, and contracts, making it easier to collect and manage data. Many PDF Forms can be filled out using software like Adobe Acrobat or online tools, ensuring accessibility and convenience for both creators and users.
