How to use PDF Form Filler

Upload a fillable PDF. Every form field it contains is listed automatically — type into text fields, tick checkboxes and choose dropdown values. Optionally tick 'Flatten' to bake your answers permanently into the page, then download the completed PDF.

Frequently asked questions

What types of form fields are supported?

Text fields, checkboxes, radio button groups, dropdowns and option lists. Digital signature fields cannot be signed here — use the PDF Watermark tool to place a signature image instead.

What does flattening do?

Flattening draws your answers directly onto the page and removes the interactive fields. The values can no longer be edited, which is useful when sending a final copy.

My PDF shows no fields. Why?

The document has no interactive AcroForm fields — it is either a flat document or a scan. A form you can only type into in Acrobat's 'Fill & Sign' mode is not a real form field.

Is my form data uploaded anywhere?

No. The PDF is parsed and rewritten entirely in your browser. Nothing is sent to a server.
