The preview mode is not available in Windows OS since it’s an inbuilt Mac OS feature. Preview helps in previewing music, videos, pictures, etc. without executing the program software. You can also convert the filetype of images from JPG to PNG, PNG to GIF and any other image format combination. You can even encrypt and lock PDF files using the Adobe Acrobat software, however, I find this preview option really quick, simple, and easy to use without any heavy software usage. Let’s get started by locking a PDF file.

We will be using the same inbuilt Preview feature in Mac OS. Without further ado, let get started with simple steps.
Changing PDF password in Mac OS
First, you need to have a PDF file with password protection enabled, I mean a PDF file locked with the password. And you also need to have an existing password since you need to unlock the PDF file before changing the password.
Visit the location where the new PDF export has been saved. Check if the new export is getting unlocked with an old password (I’m 101% sure it won’t). And later try unlocking with the new password. You’ll have the two files with a different password, you can discard the PDF file with the old password to continue using with the newly changed password.
