Using PDF Actions for Automation
Use PDF Actions to automate the process of setting security to PDF documents. For instance, if you need to add the same password and permissions for documents on a recurring basis, create a PDF Action for this task and save it. You can then simply reuse the action next time you have to set passwords and permissions to a document. You can also use the Apply Actions to a Batch function to set security for multiple documents in a single click. See our documentation on PDF Actions to learn how to create them.
Setting Security to a Batch
To set security to a PDF document that is not opened in PDF Studio or to set security to multiple PDF documents in a single action, use the Set Security to a Batch Function. See our documentation on Setting Security to a Batch in the Batch Process documentation page.
