Hi,
can I lock a pdf after I have filled a form to avoid the receiver being able to change it? I tried with password security on editing, but that only takes care of the text outside of the form fields that I have filled in manually. Is there a solution to this?

After filling the form fields you can disable form filling at password security.

The best way to do that is to digitally sign the file.
