Unlock PDF Files Using Free Online Tools

Password protection helps keep sensitive PDFs secure when you share them. But if you need to edit a password-locked PDF, entering the password every time you want to open it can slow you down.

A simple way to unlock PDF files you own and remove their passwords is to use a PDF unlock tool, such as QuillBot’s free online PDF Unlock.

Removing the password protection from a PDF you own because you want to save time when opening it is easy with an online PDF unlock tool.

Step 1

Locate the password-protected PDF on your device and upload it to the PDF unlock tool.

Step 2

When prompted, enter the PDF’s password so the tool can unlock the file.
