Frequently asked questions

Can I fill out any PDF form?
Yes. All standard interactive fields are supported: text, checkboxes, radio buttons, lists, and signature fields.
What does it mean to "flatten" a form?
Flattening transforms inputs into permanent PDF content: fields disappear and values can no longer be modified.
Can I create my own forms?
Yes. Add fields to an existing document and configure their properties (label, format, behavior) before distribution.
Can I start from scratch after filling it out?
Yes. Resetting clears all inputs at once, and unlimited undo (Ctrl+Z) also allows you to go back step by step.
