Frequently asked questions
What does flattening a PDF mean?
Converting interactive elements (fields, checkboxes, annotations) into fixed page content, as if printed.
Is what I typed in the form kept?
Yes: the filled text becomes part of the page; what disappears is the editable field.
Is it reversible?
No. Keep a copy of the original if you might need editable fields later.
Does it flatten added signatures too?
Signatures drawn as images are already fixed content; form signature fields get locked when flattening.
