用內置 PDF 編輯輕鬆填寫表單

Filling out PDF form fields allows users to enter information directly into interactive elements within a PDF document such as text boxes, checkboxes, dropdowns, and signature fields. This functionality transforms static PDFs into dynamic fillable forms that can be completed digitally, reducing the need for printing or manual data entry. The ability to fill, validate, and submit forms directly within a PDF viewer improves efficiency, accuracy, and user experience while supporting accessibility and cross-platform use. Common use cases include completing applications, registration forms, surveys, contracts, and approval documents, making it an essential feature for businesses looking to streamline document-driven workflows.
