    PDF Form: Lock information after it's filled

    Asked by CDintern on March 18, 2015 at 09:52 PM

    I don't know if this is something Jotform normally helps with...but now that we have our PDF working, is there a way to send it, have someone fill in the form, and then have it lock once they enter information.  So afterward, when they send their completed form out, no one else will be able to edit their information?

    I think this is more of related to the PDF app feature which Jotform does not have control over. This guide from adobe PDF might help but it requires a few steps. https://forums.adobe.com/thread/1004168

    Just FYI, PDF form can also be submitted directly on the PDF (using adobe reader or foxit reader) by hitting the submit button. It works similarly when you submit the web form.

    Hope this helps. Thanks!
