How to use it
- Choose a PDF containing AcroForm fields.
- Fill supported text, checkbox, and choice fields and decide whether to flatten.
- Download the filled PDF or a field-value JSON file.
Helpful tips
- Flattened fields become page content and cannot be edited again.
- XFA, digital signatures, and permission-restricted fields may not be editable.
- A scanned image is not an interactive form; use PDF Signature or OCR instead.
Frequently asked questions
Which fields are supported?＋
Common AcroForm text, checkbox, dropdown, radio, and option fields are supported. Buttons and existing signature fields are not rewritten.
What does flatten mean?＋
Flattening fixes field appearances onto the page so PDF readers no longer treat them as editable fields.
