4 Things to Try When You Forgot PDF Password

By Roche | Follow twitter | Updated on January 12, 2023

When you attempt to open a PDF file but forget the PDF password, the first thing is to try different passwords until you finally give up. At that time, you must have regretted setting passwords for the document. So, any good ideas for how to access the PDF even though you lost or forgot the PDF password?

If not, put down all your concerns. This post is going to cover some actionable ways to crack a password-protected PDF on the condition that you don’t know the file password.

What Is PDF Password Protection?

First and foremost, we should make it explicit: what is PDF password protection? Technically, password protection refers to two-layer passwords: an open password and an owner password.

The open password is used to restrict unauthorized users from opening, viewing, and accessing PDF documents. While the owner password (also known as permission password) lets unknown readers view the document, further actions, including but not limited to printing, copying PDF text, editing the content, or leaving markups on the PDF file, are not allowed. Hence, it is crucial to figure out which kind of password is protecting your PDF.

Notably, when it comes to cracking the PDF file password and opening a secured PDF, we usually talk about removing the owner password.
