How to remove PDF protection. In the article How to remove PDF password we learned how to access a file protected by a password. Today we will deal with a similar discourse, however, trying to use other tools. Also in this case we refer to PDF files that are protected and for this reason they are not visible or cannot be editable. There are some free online services that allow us to remove the protection from PDFs making them perfectly accessible. Here then, within this guide proposed a tutorial to understand how to remove PDF protection using some online services.
We remind you that there are two types of passwords that can be attributed to PDF documents: owner password, and user password. The former are easier to remove and generally prevent documents from being edited or printed. While the latter even prevent the document from being displayed. But let’s go in order. Let’s start with the owner passwords and understand what tools can be at our disposal to circumvent this protection.
How to remove PDF protection.
Owner password: QPDF
A first proposal in these terms is a QPDF software. It is a free resource that adapts perfectly to all operating systems. It does not have a graphical interface and is generally used by means of commands.
- download the program
- complete the download
- open the zip folder
- extract the software
- start the program
- hold down the Shift key
- click on the bin folder
- click on open command folder here
- run the command qpdf –decrypt input.pdf output.pdf
If you use a Mac instead, you will need to use Homebrew to download the program. In case you haven’t already installed this package manager proceed.
- open the terminal
- type the following commands:
- /usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)” to install Homebrew (you will need to type your account password on macOS).
- brew install qpdf to install QPDF
Now the installation is complete, so proceed by entering the command: qpdf –decrypt input.pdf output.pdf
Portable PDF Unlocker
If you feel that the above program requires too much practice, this is a much simpler proposition. Portable PDF Unlocker is an easy-to-use program that allows you to remove protections from PDF files by dragging them into its main window.
- download the program
- open package package 7z
- extract the 7z file
- and copy them to a folder of your choice
- open the program
- drag a PDF file you want to unlock into the main window
the game is done!
iLove PDF
Another very good resource in this regard is iLove PDF. We are talking about an online service that allows you to convert files into other formats but also to unlock them if they are provided with binding protection.
