There are three PDF Security Options available. Security options in the Print dialog's 'Save as PDF' drop-down menu allow users to password protect PDFs. This hidden talent should benefit any Mac user who needs a more secure way to share documents and files. You’ll see a new set of choices the one you want to select is called 'Security Options.' This is where the secure PDF magic sits, and you can set passwords to open documents, to copy content out of the document and to print a document.Click that menu and then choose 'Save as PDF' in the options that appear.
It can be in any file format (Word, PDF, Pages, etc.) that you can print on your Mac.
