If you want to encrypt a PDF on a Mac, the least complicated system is to use the Preview application. You can use Preview to add a password to your most sensitive PDF files to keep them secure.
Preview is readily available as a main macOS app, so you are going to come across it on any Mac computer system. There is no more software required—all you will need is a PDF document to encrypt and a Mac to encrypt it with.
If you’d choose to use other program, you can password-guard PDFs applying Microsoft Office in its place, but Preview offers the quickest way to do it making use of a core Mac app.

To increase a password to a PDF document on macOS, open the Preview application from the Launchpad, which you can launch from the Dock at the base of your Mac’s display.
Alternatively, you can start Preview from the Applications folder in the Finder app—you’ll also come across this as an icon on your Dock.
When Preview is open, click on File > Open up from the menu bar to open up the PDF doc you want to encrypt with a password.
To start encrypting the PDF document you’ve opened in Preview, click File > Export from the menu bar.
This will carry up several selections to export your PDF in diverse formats, including the alternative to include a password.
If you do not want to overwrite your current doc, you are going to need to have to give your new doc a title in the “Export As” box. Validate the help save spot under the “Where” fall-down menu.
To insert a password, click the “Encrypt” checkbox in the options menu and then sort a safe password in the “Password” and “Verify” boxes immediately underneath.

Press the “Save” button to help you save your encrypted PDF doc once you have confirmed your configurations.
Your PDF document will then be exported employing the choices you’ve picked. Loading the document in Preview immediately after the file has been encrypted will call for you to insert a password.
Sort in the doc password in the “Password” box and then push Enter on your keyboard.
If the password is proper, this will decrypt the file and open the document. You will be in a position to proceed viewing the file until eventually you near it—once shut, you will need to re-enter the password to perspective the file once more.
