How to use Fill PDF Forms

My PDF shows no fields — why?

It is probably a flat scan, not a real form. Try OCR or Annotate instead — this tool needs embedded form fields.

What happens when I flatten?

Fields become permanent static text that can't be edited — ideal before sending contracts and applications.

Which field types are supported?

Text fields, checkboxes, and dropdowns. Unsupported types are listed and left untouched.
