Make supported form fields non-editable

FileFit uses the PDF form structure to flatten supported AcroForm fields. Keep your original editable PDF as a backup. XFA forms and unusual PDF form types may not be supported.

FAQ

What does flattening mean?

The current values of supported form fields are merged into the document appearance so the fields are no longer editable.

Should I keep the original?

Yes. Keep the original PDF if you may need to edit the form later.

Flatten only after checking all answers

Flattening can make entered form values part of the output page appearance, but it may remove the ability to edit interactive fields. Keep the unflattened original and inspect every answer after export.
