Hi @victoria_5505,

 

Thanks for reaching out. 

There could be multiple reasons for it: the file is already signed with a digital signature, the file is already password-protected, etc.
You can check how to secure a document: https://adobe.ly/47wVkLp

 

 

To check a PDF file’s restrictions in Adobe Acrobat (or even Acrobat Reader), you can follow these steps:

 

1. Open the PDF in Acrobat or Reader

  • If it’s password-protected, you may be prompted to enter the password first.

 

2. Go to Document Properties

  • Windows: Press Ctrl + D
  • Mac: Press Cmd + D
  • Or go to File > Properties.

 

3. Switch to the “Security” tab

  • You’ll see the Security Method (e.g., No Security, Password Security, Certificate Security, etc.).
  • Printing allowed/not allowed
  • Content copying allowed/not allowed
  • Page extraction allowed/not allowed
  • Commenting, form filling, signing, etc.
    Below that, the Document Restrictions Summary lists permissions such as: 

 

4. Interpret the results

  • If restrictions are in place, they will be marked as “Not Allowed.”
  • If you see “Security Method: No Security,” there are no restrictions.
