Protect your JavaScript from copying and tampering
JavaScript Obfuscator transforms readable browser-based JavaScript into protected code that is difficult to understand, copy, or tamper with, and has operated since 2004. It offers both an online obfuscator and a Windows desktop app that protects folders and embedded JavaScript in HTML, PHP, ASP, ASPX, and JSP files. Multiple protection presets and local processing keep source code secure on the user's own workstation.
