About this tool

Form Creator adds interactive AcroForm fields to an existing PDF. Pick a field type — single-line or multi-line text, checkbox, radio button, dropdown, list, signature or button — and drag on the page where it should go. A single click places a field at a sensible default size.

Select a field to set its name, default value, options and whether it is required. Radio buttons that share a group name work together; duplicate a field to build rows quickly.

The result works in Adobe Acrobat, browsers and mobile PDF apps, and can be filled with Mofumi's Form Filler. Everything runs locally.

Frequently asked questions

How do radio buttons work?

Buttons with the same group name belong together; only one can be selected. Give each an export value.
