How to password protect a PDF file in Mac OS without any software app?

You can quickly encrypt or lock a PDF file in Mac OS in preview mode without install any PDF locker app or Adobe Acrobat software.

I know it sounds catchy but, you can actually password protect a PDF file in Mac OS without using any software, all you need is a preview mode in Mac OS machine, and the encrypted file will be created in no time.

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 file 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 with locking a PDF file.
