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.
The 'Low (150 dpi)' setting allows printing, but the quality will be basic, often good enough for reading but not for professional use. 'High' allows printing at the best possible quality your printer can achieve. You would choose 'Low' to let people print for review but not create high-quality copies, while 'High' is for when you trust users with full-quality prints.
The owner password acts as a key to unlock the security settings on a PDF. It ensures that only the person who set the restrictions, or someone they trust, can change them. This prevents unauthorized people from altering or removing the security measures you put in place, keeping your document safe.
When you use 'Restrict Permissions', you can choose to prevent copying of text and graphics. If you set this option, people will not be able to select and copy content from your pricing proposal. This is important for protecting sensitive information and intellectual property within your document, ensuring your data stays where you intend.
