Encrypt & Decrypt Files password-protects any file — PDFs, documents, photos, archives — with AES-256-GCM encryption using your browser’s built-in Web Crypto API. The key is derived from your password with PBKDF2 (600,000 rounds), and even the original file name is hidden inside the encrypted file. To open it again, drop the encrypted file here and enter the same password.
