Intro

This single-page tool helps you obfuscate JavaScript locally in your browser. It uses a JS obfuscator library in-browser and performs a simple minify option. Nothing is sent to a server — all work happens client-side.

Why use JavaScript obfuscator?

  • Make source code harder to read (protect IP / deter casual copying).
  • Reduce direct exposure of variable names and function names.
  • Combine with other build steps (minify, bundling) for production.

How to use

  1. Paste or upload your .js file into the Input area.
  2. Click Validate to check for syntax errors.
  3. Optionally click Format or Minify (simple).
  4. Click Obfuscate to produce an obfuscated output.
  5. Compare sizes and Download or Copy the result.
