Does this keep the answers?

No. The value goes with the field. Export first if you need them.

How is this different from flattening?

Flattening keeps the answers as page content. This deletes them.

What if a name does not match?

It is reported rather than ignored.

Remove PDF Form Fields

Delete fields from a form, or strip the form entirely.

How it works

Removes named fields, or every field if you name none. Removing a field deletes its value too, so export the values first if the answers matter. When the last field goes the empty form container goes with it, which stops readers announcing a form that no longer exists.
