इस टूल के बारे में: Protect PDF
Contracts, payslips and ID scans should not be readable by anyone who happens to get the file. The Protect tool encrypts a PDF with a password of your choice, so it asks for that password before it opens.
We cannot recover your password. If you forget it, the file cannot be opened — keep it somewhere safe.
यह कैसे काम करता है
- Add your PDF. Drag it in or choose it from your device.
- Choose a password and type it twice to be sure.
- Protect. Press Protect PDF to encrypt the document.
- Download the protected file and share the password separately.
Why use Protect PDF
- Password encryption applied on our server — nothing to install.
- Your password is only used to encrypt the file.
- Files up to 50 MB; no account required.
अक्सर पूछे जाने वाले सवाल
Can you recover my password?
No. We cannot reset or recover passwords, so a forgotten password cannot be undone. Store it in a password manager.
Is my original PDF changed?
No. Your original stays on your device; you download a new, password-protected copy.
What makes a good password?
A long phrase you can remember — a few unrelated words is stronger than a short mix of symbols.
