Frequently asked questions
Can I allow form-filling but block document editing?+
Yes — the permission model allows fine-grained control: enable form-fill while disabling general editing and annotation.
Will this prevent edits in Adobe Acrobat Pro?+
Adobe Acrobat Pro respects owner permissions when they are combined with encryption. Without encryption, permissions are advisory only in some tools.
Do I need to combine this with an open password?+
Not required, but recommended for sensitive documents — combine with an open password for full access control.
