How to flatten a PDF

When should you flatten a PDF?
Flattening is useful before sharing, printing, or archiving a completed form. It is not the same as password protection or a digital signature.
Keep the editable original
Flattening is normally irreversible in the downloaded copy. Keep the original if its fields or annotations may need editing later.

Frequently asked questions
What does flattening a PDF do?
Flattening converts interactive form fields and annotations into fixed page content so they are no longer editable as separate objects.

Can I flatten a password-protected PDF?
A protected document must be unlocked with the correct password before it can be flattened.
