- 2.Select Flatten PDF to make its form fields non-editable.
- 3.Download the flattened copy and verify that every value remains visible.
When should a PDF be flattened?
Flatten before sending a finalized form to a client, submitting a completed application, or archiving a version whose field values should not be casually edited. Keep the original editable PDF in a safe location.
Flattening is not encryption
Flattening removes interactive form behavior, but it does not add a password or prevent every possible modification. Use Protect PDF when access also needs a password.
