Top 3 Methods to Learn How to Unlock PDF on Mac

Part 1. Why is the MacBook PDF File Locked?

A PDF file on a MacBook may be locked using two types of passwords: an open password and a permission password. An open password is required to access the PDF content, which means that the file cannot be opened without this password. On the other hand, a permission password restricts specific actions, such as editing, printing, or copying content from the PDF, but allows users to open and view the files.

There are two primary reasons why a MacBook PDF file might be locked. First, it could be to protect confidential information and ensure that only allowed individuals can access the document. Second, the lock might be in place to maintain control over the file's distribution and usage to prevent unauthorized modifications or sharing of the content. It is essential to understand the specific type of restriction to find the right Mac unlock PDF method.

Preview is a built-in feature of macOS that allows users to view PDFs and images easily. If the user has the password to the locked PDF file, they can effortlessly edit the permissions and remove the password to unlock the PDF. Moreover, they can keep the PDF locked but alter the permissions to give others limited access to the content. Examine the steps below to study how to unlock a PDF in Preview:

You can perform this removal procedure only if you know the PDF password. Hit the “Apply” button to finalize the settings accordingly and save the unlocked PDF.
