Add strong encryption to your PDF documents in seconds. Follow these steps:

Upload PDF: Select the file you want to secure.
Set Password: Enter a strong password. You will need this to open the file later.
Encrypt: Click "Protect PDF". We will encrypt your file securely.
Download: Save your protected PDF. The password is now required to view it.

For security reasons, we cannot recover lost passwords. If you lose the password, the file cannot be opened.

Yes, we use standard encryption. However, very weak passwords (e.g., "1234") are easier to crack, so choose a complex one.

Is this PDF protection tool free?

Yes, Sj480 allows you to password protect your PDF files completely free of charge.

Can you open the file if I lose the password?

No. We do not store your password or your file content. Once encrypted, only someone with the correct password can open it.

Is it safe to upload confidential documents?

Yes. All file transfers are encrypted via SSL. Your uploaded files are automatically deleted from our servers permanently after one hour.
