Flatten PDF
Lock in the answers of a filled PDF form. Flattening turns every form field into normal page content, so it can no longer be edited and displays identically in every PDF reader and printer.

Frequently asked questions
Can I undo flattening?
No. The answers become part of the page. Keep a copy of the original file.
Why do my answers disappear in some apps?
Some apps do not display form fields properly. Flattening fixes this by making the answers regular content.
What if my PDF has no form?
The tool tells you there is nothing to flatten.
