4 Ways To Password Protect PDF on Mac.
PDF is the most commonly used format for published documents. Its availability on all OS platforms and all devices makes it a common platform for the exchange of any document. From a security point of view, PDF is generally a read-only format and its contents cannot be easily edited, but sometimes you feel the need to password protect your PDF so that no one can access the content at all. Or, if you are sending a file to someone, you want only that person to be able to read the content.

If you have any doubts about protecting your PDFs, it depends on what type of protection you have applied to your file. If you use a simple third-party application to set a password to open a file, it could be hacked by an application that does not recognize this locking function. You may even find that your browser can directly open the password-protected PDF file you just received by email. To avoid hacking, I recommend that you use software that encrypts the contents of your file (preferably 128-bit), not just a simple password.
Method 1: Password protect the PDF file on Mac natively
Step 1:
Find and open the PDF on your system using the default Preview application. The file must be open for you to set a password.
Step 2:
Click the File tab on the menu bar and look for the Export option. Not to be confused with Export to PDF.
Step 3:
Click Export to see options for saving duplicate files. The process saves a duplicate file to the destination of your choice.
The fourth step:
Check the box in front of Encrypt to assign an access code to the file. The set access code will be applied to the new file. The original file will remain unprotected as before, or if you had a password for the original file, it will remain intact and unaffected. The preview uses RC4 128-bit encryption.

Most PDF documents are created using editing software and then exported to PDFs. If you are in the process of creating a document that you later want to convert to a password-protected PDF file, you do not need to spend energy saving the PDF and then following the steps above to fully export another PDF. You can do it right here on Pages, let’s see how.

Setting a new password for the newly exported PDF will not affect the password for the original Pages document.
Alternative:
You can follow step 3 and export an unprotected Pages. When exporting, select Require Password and set a new password for the exported PDF. It also won’t affect the original Pages file.
Method 3: protect PDF password online
There are a number of websites to help you do your best for the PDF file. One such site is Smallpdf. It has all the functions you can name and gets the job done pretty well and quickly. Services are paid for obvious reasons, but they allow you to perform two tasks (any) per hour for free. So if it’s not a large part of PDF documents, you can encrypt your PDF here. Yes, it uses AES 128-bit encryption, so it’s pretty secure.

You can even remove the password with Smallpdf PDF Unlocker. It claims to remove the password of some simple password-protected PDFs even if you don’t know it. But if he cannot do this, he will ask you for a password, which is pointless as you can easily remove the password in your macOS Preview app. Read below to find out how.

Password protect PDF files on macOS
There are several ways to password protect a PDF file on macOS without using a third party application. You might think that I am missing MS Word here.
