How to save a read-only copy of pdf file

[pdfman123]

I have PDF-XChange Editor Plus, Version 9.3, Build 361.0

I want to be able to save a fillable PDF form as a non-fillable one while preserving all content that I have already entered. For example, say, your PDF form asks you to manually enter your name and current date. After I enter them, save PDF, close and reopen it, I can still change both of these fields. I want to be able to save a copy of this PDF that has all the fields I have entered, but no longer allows me to change them. Does anyone know how to do it?

Hi pdfman,

if you add document security you can include options to not be able to fill the form fields:

See the sample. I think this is what you want?

This KB details how to add document protection, it can be a password or a digital certificate:

I hope that helps, let me know how it works out for you?
