Frequently asked questions
Why should I flatten a PDF?
Flattening locks form fields and annotations, converting them into standard page text so they can no longer be modified or selected separately.
Can a flattened PDF be unflattened?
No, flattening bakes form fields directly into the page layer for permanent security.
