Frequently Asked Questions
Related Questions
Can recipients still edit the form fields after flattening?
No. Flattening bakes the form values permanently into the document's vector streams, making them unalterable.
Does flattening reduce document clarity?
No. Your filled text, checkboxes, and signatures retain their sharp vector rendering.
