We add passwords to PDF files for security enhancement, so our privacy can be protected. But, in case that you want to remove restrictions of your password-protected PDF files, or in case that you lost the user or open PDF password, do you have any idea to unlock the PDF on mac without a password?

Here we are going to list you some easy solutions, you can use handy PDF unlocker app or free methods to unlock PDFs on Mac online or offline.

Basic Knowledge about PDF Passwords

It would be better for you to have general information about PDF password if you want to unlock password-protected PDF files by using the right password. The PDF password is categorized into 2 types as follows:

PDF Owner password---also named as permission or master password, which specifies operations that should be restricted even when the document is decrypted. Without the owner password, you do not have permission to print, to copy portions of the document, to create or modify annotations in the document, nor to modify the file.

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 and you don’t know the password.

    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.
