I'm about to upload a detailed medical summary for [client=Tomas] to the shared clinic drive but need to restrict view…
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.
'Changes Allowed' controls what types of edits users can make to your PDF. If you set it to 'None', users cannot insert, delete, or rotate pages. They also cannot fill out forms or extract pages. This is important for keeping the document's content and structure exactly as you intend, especially for sensitive documents like medical summaries.
Whether a recipient can fill out form fields depends on your 'Changes Allowed' setting. If you set 'Changes Allowed' to 'None', they will not be able to fill forms. If you want them to fill forms but not make other changes, you would need to choose a more specific 'Changes Allowed' option, like 'Filling in form fields and signing existing signature fields'. This allows form interaction while still protecting the core document content. Always test your settings before sharing.
The 'Owner Password' is crucial because it's the only way to later change or remove the restrictions you've set on a PDF. Without it, even you cannot modify the permissions, such as allowing printing or editing again. It acts as your master key to manage the document's security settings, ensuring you retain full control over your Medical Summary's access rules.
