About PDF Password Protect
Some documents simply should not be opened by just anyone. Contracts, payslips, medical records, and financial statements all carry sensitive details, and emailing them unprotected is a risk. Adding a password is the simplest way to keep prying eyes out.
This tool locks your PDF with a password so it can only be opened by someone who knows it. You set the password, apply it, and download a protected file ready to share securely. The service is free, runs in your browser without signup, and adds no watermark, so your document stays private and clean. Just remember the password, because you will need it to open the file later.
Common uses
- Protecting payslips and bank statements before emailing them
- Securing contracts and legal documents shared with clients
- Locking medical or personal records stored on shared devices

FAQ
What happens if I forget the password?
There is no way to recover it for you. Store the password somewhere safe, because without it the file cannot be opened.
Can I remove the password later?
Yes. As long as you know the current password, you can unlock the file again using a password removal tool.
How strong should my password be?
Use a mix of letters, numbers and symbols. A longer, unique password is much harder for anyone to guess.
Can I use PDF Password Protect on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
