PDF Protector
Add password protection and encrypt your PDF documents. Secure sensitive information with industrial-grade encryption.
Security Settings
Passwords are required to open the document. We recommend at least 8 characters with numbers and symbols.
Your password never leaves your browser. Encryption is performed locally using the Web Cryptography standard.
Secure Your Sensitive Documents
Protect your intellectual property, financial records, and private documents with industrial-grade PDF encryption. Our PDF Protector allows you to lock any PDF file with a strong password in seconds.
Because the encryption occurs directly in your browser, your unencrypted files never leave your device. This makes it the safest choice for handling confidential business or medical data.
