Secure your sensitive documents with a password using robust encryption. Our Protect PDF tool allows you to lock your files so only authorized people with the password can open them. Essential for emailing contracts, financial statements, or personal data.

How to password protect a PDF:

1. Select your file: Upload the PDF you want to secure.
2. Set a password: Enter a strong password. We recommend mixing letters, numbers, and symbols for maximum security.
3. Encrypt: Click 'Protect PDF'. Your browser will encrypt the file locally and provide a download link.

Security Features:

• Standard Encryption: Uses reliable PDF encryption that works with all major PDF readers (Adobe, Preview, etc.).
• Client-Side Processing: Your password and file never leave your computer. We cannot see your password.
• Instant Protection: Secure your files in seconds without installing heavy software.

Important Note

Please remember your password! Because the encryption happens on your device and we don't store your data, we cannot recover a lost password.
