Fill in a PDF form

Populate a PDF's text fields, checkboxes, dropdowns and radio buttons from a simple field=value list.

Mae's Fill PDF Form tool reads every AcroForm field in your document — text boxes, checkboxes, dropdowns and radio groups — lists their names so you know exactly what to fill, then applies the values you supply as "field name = value" lines, one per line. Pair it with Flatten PDF afterwards to lock the answers in.

Frequently asked questions

How do I know what field names to use?

Upload the PDF first — Mae lists every field name and its type in the result, so you can copy them into your field=value lines.

How do I check a checkbox?

Use a value like true, yes, 1 or checked; anything else leaves it unchecked.
