Please note that all the descriptions are based on the fact that you do remember the PDF password. What if you have no clue what the passwords are? SwifDoo PDF, a trustworthy password remover, is the answer. Let’s dive into how to tackle PDFs locked for editing. 

How to Unlock a PDF for Editing

When we mention password protection, it actually refers to the owner password (also known as the permission password). An open password is unbreakable and cannot be bypassed. To put it simply, without an open password, no one can access the PDF content.

The owner password is employed to confine certain actions, such as printing, editing, annotating, or copying. Therefore, if your PDF is locked for editing, SwifDoo PDF can edit a secured PDF without password.

How to remove password protection from a PDF

SwifDoo PDF can easily circumvent and get rid of the owner password protection. As a consequence, users can unlock a PDF before editing. Have a look at how to do it:

It’s time to edit this PDF without a password.

This article offers two simple approaches to editing a secured PDF. No matter if you remember the PDF password or not, SwifDoo PDF can be your trusted partner to unlock a PDF for editing.

Once again, all the password removers on the market target permission or owner passwords rather than open passwords. Be careful when a program claims it can deal with an open password or user password.
