A pre-fill form is a digital document or online form that has been partially completed with information that has been previously entered or selected by the user. This feature allows for a more efficient and streamlined process, as the user does not have to manually input the same information multiple times. Pre-fill forms are commonly used in various applications, such as online registrations, surveys, and e-commerce checkouts. They not only save time and effort for the user, but also reduce the risk of errors and ensure accuracy of the information provided.
