Not all PDF documents are created equal. An **interactive fillable PDF form** contains electronic **AcroForm** data fields (such as text boxes, checkable boxes, radio groups, and drop-down lists) built into the PDF file structure. When you open an interactive form, field boundaries light up and allow digital typing and selection.
In contrast, **scanned or flat PDFs** are static page images or text pages that do not possess embedded electronic form field tags. If your PDF is a scanned paper document or a non-interactive PDF, our Fill PDF Forms tool will inform you that no interactive fields were detected. For scanned documents, you can use our Flatten PDF or Sign PDF tools to add signatures or manual text overlays.
Fill out names, addresses, job titles, descriptions, and notes in standard PDF text fields.
Check or uncheck boolean agreement boxes, terms confirmations, and multi-select options.
Select valid choices from pre-configured country, state, category, or numerical drop-down lists.
Pick single mutually-exclusive options such as Yes/No, Gender, or Account Type.
