A password-protected PDF file is something you will invariably come across as part of your business or personal communication. Usually people set passwords for PDF files considering file security, i.e. to prevent the important information from getting into the "wrong hands". Once passwords are imposed on PDF documents, they are limited only to those who have the right passwords. However, it is often the case that we've accidently lost or forgotten passwords, or just receive an encrypted PDF file but get no access. So how can we open  PDF without password? Every problem gets a solution, and this is not an exception of course. In this article, we will help you perfectly iron out this issue.

Part 1: Can Google Drive Open PDF Without Password?

Google Drive is said to help remove passwords from protected PDF files and here we'll have a check. Before getting started, please make sure that you have a Google account and have signed in to your Google Drive. Next let's begin by following the "standard" process.

Step 1: Launch your Google Drive. Just visit https://www.google.com/drive on your browser.

Step 2: Change a few settings of Google Drive by clicking on the Cog icon on your Google Drive screen and choose "Settings" on the top right corner.

After that, many tutorials claim that you'll be able to open the file and download it as a Word file with the original PDF content unchanged. However, after our "experiment", we find it doesn't work. It only works for PDF files with only permissions password. Therefore we cannot rely on this so-called solution to open a secured PDF without password.

Part 2: Can Online Tools Open PDF Without Password?

Recently, an increasing number of people turn to online tools for help with locked PDF documents. Simple to use and multi-functional as they seem to be, we do need to take a close look before we confirm that online tools can help open PDF without password. Let's try a popular one named "Smallpdf".

Step 1: Launch your browser and visit https://smallpdf.com/.

Step 2: Select "Unlock PDF"on the homepage. Choose or drop the encrypted PDF file in the PDF Password Remover.

To our disappointment, right after uploading the file, password is required to contiune the process. Therefore this method doesn't work either. Online tools still need password to unlock PDF.
