JS Obfuscator

What is JS Obfuscator?

JS Obfuscator is a free browser-based tool that scrambles your JavaScript code and optional CSS to protect it from prying eyes. You can pick from presets or fine-tune settings like control flow flattening, string array encoding, or dead code injection. Everything runs locally in your browser without sending any code to servers. Premium users get domain locking, expiration dates, and extra CSS protection. It’s easy: paste or upload your files, hit obfuscate, then copy or download the secured result.
