If you've received a PDF file that is password-protected and you don’t have the password, there are a few methods you can consider to unlock or reset the password—provided you have legal permission to access the content.
Common Ways to Reset or Remove a PDF Password on Windows:
1) Ask the Sender
The most straightforward and ethical approach is to contact the person who shared the file and request the password.
2) Use Adobe Acrobat (Paid Option)
If you have access to Adobe Acrobat Pro, you can open the PDF (with the password), go to File > Properties > Security, and remove the password. However, this only works if you already know the password.
3) Free Online Tools
There are several free online PDF unlocking services, but be cautious when uploading sensitive or confidential documents. Data privacy is a major concern with these services.
4) Use a Reliable Desktop Tool – SysTools PDF Unlocker
If you're looking for a secure and professional solution on Windows, SysTools PDF Unlocker is highly recommended. This tool allows you to:
a) Remove restrictions like printing, copying, and editing
b) Unlock owner-level protected PDFs
c) Retain file integrity and original formatting
d) Work offline – ensuring security of sensitive data
Note: For user password-protected files, you’ll still need the correct password to remove restrictions—no tool can legally bypass that without it.
Important Reminder:
Always ensure you have proper authorization to unlock or access password-protected PDF documents. Using such tools without permission can violate privacy laws or user agreements.
