Plumsail Protect does not disable fillable form

I am using the Power Automate to populate a PDF form, then perform a merge with another PDF. I have that working fine. But the fillable form that is used in the Populate stage still allows edits after the merge. I tried to use the Protect function, thinking it would disable the form fields. But it does not prevent entry into those fields. Is there a way to "seal" the fillable form so that the entire document is un-editable?

Hi @senordude,

You can try the "Lock PDF form fields" option in Processes

The possible scenario is:

  1. Set up a Process and upload the PDF form there.

  2. Activate the "Lock PDF form fields" option

  3. Call the Process using "Start Documents process action" in Power automate. It will return the "sealed" PDF.

  1. Finally, merge the "sealed" PDF with another one in the flow.

Best regards,
