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.
Set a permissions password when prompted.
CautionIf you forget this password, you cannot change or remove the restrictions later.
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.
Best practiceTest your restricted PDF in a different PDF reader or with a different user account to confirm the permissions are enforced.
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.
Choosing 'None' completely stops anyone from printing the PDF document. 'Low (150 dpi)' allows printing, but the quality will be very poor, like a low-resolution image. This means text might be hard to read, and images will look blurry. Use 'None' for maximum print security.
The owner password is the key that unlocks all the security settings you put on a PDF. It proves you are the owner and have the right to change printing, editing, or copying rules. Without it, anyone could remove the protections, making the security useless. Keep this password safe.
No, if you set 'Changes Allowed' to 'None', people cannot fill out forms. This setting also stops them from inserting, deleting, or rotating pages. To allow form filling while restricting other changes, you would need different permission settings.
The 'Restrict Permissions' feature helps you control what others can do with your sensitive M&A documents. It lets you stop people from printing, editing, or copying the PDF. This is important for keeping confidential information safe and making sure only authorized actions happen with your data.
