How do I make sure no one can print my PDF document using Restrict Permissions?

Open your PDF in Acrobat. Go to the 'Protect' tool. Choose 'Restrict editing and printing'. For 'Printing Allowed', select 'None'. Set an owner password and save. This stops all printing.

What is the difference between 'Printing Allowed: None' and 'Low (150 dpi)' when restricting permissions?

When you set 'Printing Allowed: None', no one can print the PDF at all. Choosing 'Low (150 dpi)' means people can print, but only at a low quality. This is useful if you want to allow basic printing for review but prevent high-quality copies that could be misused. 'High' quality allows full-resolution printing.

Why does Adobe Acrobat require an owner password to change PDF restrictions?

Adobe Acrobat requires an owner password to ensure that only the document owner or authorized persons can change the security settings. This password protects your chosen restrictions from being removed by others. Without it, anyone could easily change the rules you set for printing, editing, or copying.

If I restrict editing on a PDF, can users still fill out form fields?

When you restrict editing on a PDF, the 'Changes Allowed' setting governs what users can do. If you want users to fill out form fields, you must specifically allow 'Form fill' when setting the restrictions. If 'Form fill' is not allowed, users will not be able to type into form fields, even though other editing is blocked.

What does 'Restrict Permissions' mean for controlling who can copy text from my PDF?

When you use 'Restrict Permissions', you can stop people from copying text or images from your PDF. This is part of the overall protection settings. By setting an owner password and choosing to restrict copying, you prevent unauthorized use of your content, making it harder for others to take parts of your document.

How to do it

the tool · the steps · what to avoid

1
Open the PDF file you want to restrict in Adobe Acrobat Pro.
2
Select File from the top menu, then choose Properties.
3
In the Document Properties window, click the Security tab.
4
From the Security Method dropdown, select Password Security.
5
In the Password Security Settings dialog, check the option to restrict editing and printing of the document.
6
Set a permissions password when prompted.

7
Choose the specific restrictions you want to apply (e.g., disallow printing, disallow editing, disallow copying).
8
Click OK to confirm your settings and close the dialog.
9
Click OK again in the Document Properties window.
10
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.

In the appWith the API

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.

FAQ

about this task

You use the API’s 'Protect PDF' feature, where you can send your PDF along with the permissions you want (like no printing or editing), and the API will return a new PDF with those rules applied.

Setting permissions controls what people can do with the PDF (like print or copy), while adding a password means only people with the password can even open the file. You can use both together for more security.

Using the API lets you set permissions for many PDFs automatically, which saves time and avoids mistakes, especially if you handle lots of files or need to do this as part of an app or website.

Yes, you can upload the existing PDF to the API and apply new permissions, but you’ll need to make sure you have the right password if the file is already protected.

PDF permissions are helpful but not foolproof; determined users might find ways around them, so combine permissions with other security steps like passwords or secure file sharing when needed.
