I'm tired of overprotecting documents so heavily that partners and procurement complain, yet we still have leaks. Acro…
Open the PDF file you want to restrict in Adobe Acrobat Pro.
Select File from the top menu, then choose Properties.
In the Document Properties window, click the Security tab.
From the Security Method dropdown, select Password Security.
In the Password Security Settings dialog, check the option to restrict editing and printing of the document.

Choose the specific restrictions you want to apply (e.g., disallow printing, disallow editing, disallow copying).
Click OK to confirm your settings and close the dialog.
Click OK again in the Document Properties window.
Save the PDF to apply the new permissions.

You can review or change these restrictions later by reopening the Document Properties and returning to the Security tab.
This runs in the Acrobat app - there is no separate API for this task.
| Option | Effect on Printing |
|---|---|
| None | No one can print the document at all. The print option will be greyed out. |

Yes, if you allow 'Form fill' in the 'Changes Allowed' settings, others can still fill out forms. You can choose to allow form filling while restricting other changes like inserting or deleting pages. This is useful for surveys or application forms.
'Restrict Privileged Access' means limiting who can perform advanced actions on a PDF, beyond basic viewing. This includes actions like changing security settings, extracting pages, or making significant edits. It's a key part of defining access controls to ensure only trusted users with the owner password can perform these sensitive operations, protecting the document's integrity and confidentiality.
