PDF Flattener
Merges annotations, form fields and layers into the page content so they cannot be edited or hidden.
Flattening draws each field and annotation into the page itself, in this tab. It is a real change rather than a locked flag: afterwards the values are marks on the page rather than form data another program can edit.
