Step 2
Click ‘Browse’ button to select the ‘Source PDF’ file that you want to encrypt.

Step 3
Then select 'Security Level' in my case I’ve chosen high 256-bit AES; Acrobat 9.0 and above. (If wish, you can give a password to open the document by ticking the 'Require a password to open the document'.)

Now click ‘Save’ button to save the encrypted pdf document. Click ‘Finish’. Now open the file with a pdf viewer and try to copy things. It will never be copied.
