When you receive a PDF file, how can you find out what is restricted on the file? You can use the below methods to find the restriction.

Open the PDF file with Adobe Acrobat. If the PDF has been locked with open password, you will get a pop-up window asking you to enter password. Now you only can get the password from the owner or use the encryption-breaking software.

If you do not need a password to open the PDF file, the file will be opened directly. Then you can view a Lock icon on the left pane. Click the icon and you will get a pop-up window showing the restriction details. Or you can click the Edit button to show the drop-down menu.
