Setting PDF File Security Options

Set the security options to restrict viewing, printing and page editing of PDF files.

Security Settings

Open a PDF file, and click Password Settings in the Edit menu to open the Password Settings dialog box.

1Select check boxes to set passwords.

•Password to open document

The Document Open password is required to open the PDF file, and is entered in a dialog box that appears when opening the PDF file.

•Password to change authority and password

The Permissions password restricts changing authority to print the file or edit a page, and is entered in a dialog box that appears when attempting to change security settings.

Important

Always set the permissions password when setting permissions. If permissions are set only with the Document Open password, security can be canceled merely by opening the document, so care should be exercised.

Note

When adding, inserting or replacing pages, PDF files which have the user password set cannot be used for addition or insertion.

2Set the password and enter the same password to confirm.
