How to obfuscate JavaScript source for harder reading

1. Paste the JS

   Drop your source into the "JS" field. The obfuscator works on standard ES2020+ syntax; module imports stay structurally intact so the result still loads as a module, but its internals look very different.

2. Press Run

   Result returns a single `obfuscated` field. Identifiers are renamed to short or random strings, string literals are extracted to a lookup table, dead-code is reordered, and control flow gets flattened where safe.

3. Why it's not security

   Obfuscation slows down a determined reverse-engineer; it does NOT make the code secret. Anything the browser runs, a debugger can step through. For real secrets (API keys, business logic) keep them on a server — obfuscating shipped JS just delays the inevitable.

4. Side effects to watch

   Obfuscated JS is bigger AND slower than the original — usually 30–80% slower for tight loops. It also breaks source-map debugging unless you generate a separate map. For production bundles, prefer minification over obfuscation.
