Do you intend to recover the password off your PDF file or totally remove the password? Just take it easy, there are many ways to recover forgotten PDF password.


When a PDF file is set by a password, you will be prevented from opening, printing or changing the file. However, with third party software, usually known as PDF password remover, you can easily recover the lost PDF password just in a few seconds. Let's check out the three best ways to recover password from PDF document.

Method 1: Recover Forgotten PDF Password Using Hastcat Utility

The first solution we'd like to introduce to you is Hashcat, a command based password recovery utility that supports recovering password from more than 10 types of files. But, this utility just supports cracking PDF files that were encrypted previously. Thus, it is not applicable for editing protection on PDF pages. You can use other available tools to remove the protection entirely without the need for cracking it.


In fact , Hashcat is still one of the fastest and the best password recovery utilities on the world, including PDF password recovery. The utility currently works with popular systems, like Windows, macOS, Linux that can help you to crack the password of PDF file as well as Excel, Word, Zip, RAR and many more.


All you need is to download the latest version of Hashcat and then unzip it to a local folder. Open Command Prompt on Windows and navigate to Hastcat folder. Now, run the hastcat.exe and start recovering password from target PDF.
