Enter Passwords When Knowing the Passwords

To begin highlighting in a PDF file, all you need to do is enter the file using the document's password. After inputting the password, your changes will be saved.

If you wish to highlight a PDF that is not yours and for which you do not have the password, you must first obtain the owner's permission. The document's owner can achieve this by changing the document's security settings. Here, you'll need the document's password in order to open it and begin highlighting.

Remove Passwords and Then Highlight PDF

There's also the possibility that you don't know the password and aren't authorized to request it from the PDF's owner. If a PDF is password-protected, highlighting will be impossible until you remove the password. A PDF password remover is the simplest method, although there are others.
