One of the best reasons to use a PDF to share information is because it’s so easy to add basic protection to the file. This video will show you how to add a password to your PDF to prevent opening or editing the contents. With the PDF file open in Acrobat DC, open the Protect tool. You may see this in your right hand pane, but if not, you can find it in the tools tab under Protect and Standardize.
In the toolbar that appears at the top of the window, choose Protect Using Password.
Here you can choose from the two options. The encryption can prevent someone from opening it at all, or can allow someone to view the file but not make any changes to it.
Enter a password, and then confirm it. Please note that this password information won’t be stored anywhere, and will not be retrievable if it’s lost or forgotten. So make sure you pick something memorable to you, or store it in a separate password manager.
Now just click apply, and the PDF has been successfully secured with your new password. -
