Obfuscated Output

What is JavaScript Obfuscator?

Need to protect your JavaScript source code? Obfuscation rewrites your code into a functionally identical but unreadable form — similar to what the open-source javascript-obfuscator project does.

According to Wikipedia, obfuscation makes code harder to read while preserving the runtime behavior defined by the ECMAScript spec. It is often paired with a minifier like Terser for production bundles.

Everything happens in your browser.
