All Tools
2 free encryption tools. Encrypt text or files with AES-256-GCM — the same standard used by governments and banks. Everything runs in your browser using the Web Crypto API. Nothing is sent to any server.
Password-protect any text. Enter text + password, get a protected string. Unlock with the same password. Share secrets safely.
Security ToolsPassword-protect any file. Drop a file, set a password, download the protected version. Unlock with the same password.
Free browser-based password protection tools using AES-256-GCM — protect text messages or entire files with a password. Share the protected output through any channel — only someone with the password can unlock it. Uses the Web Crypto API built into every modern browser. No downloads, no accounts, no data transmission.
Yes. The Web Crypto API provides the same cryptographic primitives used by professional security software. AES-256-GCM with PBKDF2 key derivation (100,000 iterations) is considered secure by NIST, NSA, and every major security organization. The encryption happens in your browser's native crypto engine — not in JavaScript — making it fast and resistant to side-channel attacks.
