Frequently asked questions

Which field types are supported?

Text fields, checkboxes, radio groups, dropdowns and option lists. XFA forms and digital signature fields are not supported and reported honestly when detected.

What does flatten do?

It bakes your answers into the page appearance so the values cannot be changed by ordinary viewers.
