Remove password encryption on a pdf in Preview
I created a pdf document, but I want to add pages to it. Unfortunately, I encrypted it with an owner password and it won't let me drag and drop additional pages into the file. How do I remove the owner encryption? I found instructions to save it using a different file name and de-select encryption in the save box. I did not have an option for encryption. I have tried using "export" from Preview and doing the same thing - de-selecting security, but again, I got no option for security when I tried that and the file I created was also encrypted.
I'm stuck. I have the password, but I can't find a way to remove password encryption.
