Have you ever seen any one of these messages when opening or modifying a PDF in Mac Preview? Most likely, and here we’d like to show you how to unlock a PDF on Mac, even without password.
We add passwords to PDF files for security enhancement, so our privacy can be protected.
There are 2 types of PDF password as follows:
PDF Owner password---also named as permission or master password, which specifies the operations that users are prevented from doing in the PDF file. These actions include creating or modifying annotations, copying portions, inserting/deleting/rotating pages, printing, editing or saving PDF. In other words, without the owner password, you do not have permission to create or modify annotations in the document, to copy portions of the document, to insert, delete or rotate pages of the document, to print, to save, or to edit this document.
PDF User password--- also named as open password, which completely encrypts the PDF file and prevents it from opening.
Also, we should know that, unlocking a PDF with owner password is much easier than that with a user password. In most cases, you cannot unlock a PDF if it is protected with a user password that you don’t know or forgot.
Most of the time, we protect a PDF and remember the password, but there is still a good chance that we get several PDFs with unknown or forgotten PDF passwords, but actually have legal rights to access to it.
Nevertheless, we have a one-stop solution to unlock a PDF on Mac under any situation for you, no matter you know or forgot the password, no matter it is a user (open) password or owner (permission) password, by using the best PDF unlocker for Mac 2025.

A professional password cracker is indispensable if you don’t know or forgot the password, especially user password.
However, if you know the password, it makes things much easier. The native application coming with macOS --- Preview can help you remove known password from PDF easily. It is a free utility to open, view, edit and manage both image and PDF files on Mac.
Looking for an online free PDF unlocker to remove PDF password protection on mac? It is lucky that we have choices. We recommend iLovePDF and PDFCandy.
This site allows unregistered users to unlock both user-password and owner-password protected PDF. However, when unlocking user password locked files, it only works when the password is quite simple, with 3 to 6 digits only. Any password with long password length, special symbols or characters will take forever to decrypt or won’t succeed at all. In this case, you’d better try Cisdem PDF Password Remover.
Although PDFCandy is less popular and well-known than iLovePDF, it is really an excellent PDF password unlocker. It collects a wealth of tools to work on PDF files, such as editing, merging, converting, creating, managing and unlocking PDF files. As a quality PDF unlocker, PDFCandy can remove both owner passwords and user passwords, while it will take some time.
There are several reasons making PDF locked, like adding password protection to PDF, setting PDF to read-only and ticking lock PDF from editing when creating a digital signature. All of measures aim to protect the private and valuable information in the PDF file.
In addition to the aforementioned cases to remove password protection from PDF, you can get the read-only mode back to read & write by right-clicking the PDF file and choosing "Get Info" > "Sharing & Permission". As for digitally signed PDF, you can unlock it to make modifications through deleting the added signature.
As a popular saying goes, every coin has two sides. Online PDF unlocker is often free, but quite feature limited, and involving risks like leakage of sensitive information. While, Cisdem PDF Password Remover provides more features for Mac users. It will be the most professional tool for you to unlock PDFs for editing, copying, printing, etc., and drive your productivity to new heights.

Impressive and I tested one encrypted file with the Unlocker, it removed the password instantly.

I bought your password remover, it can instantly remove the password protection successfully, if it can crack my open password faster(I know this makes sense cuz my password is always a little complicate), that would be perfect.
