Using PDF security settings you can limit what other people can do with your PDF. For example, you can stop other people editing or printing your PDF.

View Current Settings

To check the security settings for a PDF, choose Document > Security... from the main menu.

The security dialogue box will initially display with most controls inactive.

If enabled, click Unlock... to change security settings.

The inactive controls show the current security settings for the PDF.

If the PDF has an existing Master Password, you will have to enter it now.

If you do not know the Master Password, you will not be able to alter any of the security settings.
