Step-by-Step Guide
Upload Your PDF
Choose the PDF you want to lock with a password. Could be a contract, a personal document, or anything you want to keep private.
Set a Password
Type the password you want to use. Anyone who wants to open this PDF will need to enter this password.
Download the Protected PDF
Download your password-protected PDF. It looks identical — but now it can't be opened without your password.
How It Works
If you're sharing a PDF with sensitive information — salary slips, Aadhaar, medical reports, contracts — it's smart to protect it with a password. That way, even if someone else gets the file, they can't read it without your password.
A real example: You're emailing a PDF of your ID documents to a service provider. Adding a password means only the right person can open it. You share the password separately (by phone or text) — a common and effective way to secure files.
Good to know: Write down or save the password somewhere safe. If you forget it, no one can recover it — not even us. That's by design.
Who Uses This?

Helpful Tips
- Use a password that's easy for you to remember but hard to guess — avoid simple ones like "1234" or "password".
- Share the password via a different channel than the file — for example, send the PDF by email but text the password.
- Save the password in your phone notes or a password manager — you cannot recover it if lost.
- Don't forget to check whether the recipient can open the protected PDF on their device before sending.
Your Files Are Safe & Private
Files are transferred over secure TLS encryption and wiped automatically from server memory after processing. We never inspect, store, or share your documents.
Common Questions
