Frequently asked questions

What if the PDF has no form fields?
The tool tells you. Use Sign PDF instead, which places a signature, initials or a date anywhere on a flat page.
Can I save a partially filled form?
Yes. Download without flattening and open it again later to continue.
Which fields are supported?
Text, multiline text, checkboxes, radio groups, dropdowns and option lists. Push buttons and signature fields are listed but not editable. XFA-only forms are not supported.
