Protect PDF
Add a password and encryption to a PDF to keep it private.
🔒 Your files are processed securely over HTTPS and deleted automatically after your download.

How to use Protect PDF
- Upload the PDF you want to secure.
- Enter a password to encrypt the file.
- Click Process to apply the password protection.
- Download the encrypted PDF — it now asks for the password to open.
Frequently asked questions
What encryption is used?
The PDF is encrypted with a password, so it can't be opened without the passphrase you set.
What happens if I forget the password?
For your security the password isn't stored anywhere, so keep it safe — it can't be recovered for you.
Is this tool free to use?
Yes. You can use it for free with no account required and no watermark added to your file.
Are my files kept private?
Your file is sent over an encrypted HTTPS connection, processed on the server, and deleted automatically right after your download. Nothing is stored or shared.
