                              Frequently Asked Questions

                              What does flattening mean?

                              Flattening turns supported form field appearances into regular page content.

                              Will it work for every form?

                              It works for standard PDF form fields. Some unusual or protected forms may not flatten.

                              Can I edit fields after flattening?

                              Flattened fields are no longer normal editable form fields, so keep an original copy.
