Frequently asked questions
Why flatten a PDF?
So the answers cannot be changed, and so they print and display the same in every PDF viewer.
Can I undo flattening?
No. Keep the original file if you may need to edit the form again.
What if my PDF has no form fields?
The tool tells you; there is nothing to flatten in that file.
