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
Find and open the PDF on your system using the default Preview application. The file must be open for you to set a password.
Click the File tab on the menu bar and look for the Export option. Not to be confused with Export to PDF.
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.

Method 2: Password protect the PDF on Mac with Pages
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.
Open the Pages file you want to convert to a password-protected PDF. Click the File tab on the menu bar and find Set Password.
Click “Set Password” and enter a new password. This action will encrypt your Pages file with the passcode.
Click the File tab on the menu bar and select PDF from the Export tab.
The fourth step:
Export the file as PDF and check the box for the password. The same password will be saved for your PDF file as well. If you would like to enter a separate password, simply click the Change Password tab and enter a new password. Setting a new password for the newly exported PDF will not affect the password for the original Pages document.
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.
Open Smallpdf and click PDF Password Protect. You can even just password protect Google Smallpdf and a direct link will appear. If you are reading this on a laptop, use the PDF Password Protection link on Smallpdf.
Select your PDF document or simply drag and drop it into the selection area. The file will then download and you will be prompted for your password. After entering the password, click “Encrypt File”.
Upload your file by clicking on this link. You can even share your file directly to disk or to an email address.
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.
Method 4: How to password protect a PDF in Adobe Reader
Open the PDF file in Adobe Acrobat Reader. Right click PDF Open With Adobe Acrobat Reader.
Click Protect from the PDF editing menu on the right side of the window to view the options.
Click “Add” to set a password for your PDF document. Now if you are using the free version of Adobe Acrobat Reader, it will redirect you to a subscription page on its website and ask you to buy. These features are available in the standard free version of the app in select countries for Windows PCs only.

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. Well, if you’re using Microsoft Office on macOS, you really don’t have a direct option to convert a Word document to a secure PDF. The thing about MS Word is that even if you set a password for the Word file on macOS (menu bar tools protect), the protection will be lost the moment you save the file as PDF. So go ahead and protect your content from unwanted people.
