How do I fill a PDF form for free?

Open the Fill PDF Forms tool, upload an interactive PDF, fill in the detected fields (text, checkboxes, radios, dropdowns), and click Fill & Download. You get a flattened, filled PDF.

What fields are supported?

Text fields, check boxes, radio groups, dropdowns and option lists are all detected and editable. Signature fields are listed but not editable.

What does "flattened" mean?

Flattening burns your answers into the page as static content and removes the editable field layer, so the form is locked exactly as you filled it.

No. Fields are detected and filled entirely in your browser with pdf-lib.

Can I fill a scanned form?

Scanned forms have no interactive fields and cannot be auto-detected. Use the Edit PDF tool to type on top of the scan instead.
