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.
Password Protect PDF file in Mac OS
For this demo, you’ll need a standard PDF file in your machine. Make sure that is not already encrypted and follow the mentioned steps.
- Open any PDF file in preview mode in Mac OS
- Hit on File command from the menu bar
- Select Export to PDF option from the drop-down
- Hit on “Show Details”
- Enable the Encrypt option checkbox
- Enter a Password and Verify again
- Hit on Save button to create an Encrypted PDF file in the desired location
Now you can open the password protected PDF file from Finder and it will ask to enter the password to unlock.
