Paste JavaScript to beautify or minify

How to use

  • Paste your JavaScript into the box and click Beautify to see cleanly indented, readable code with syntax highlighting.
  • Click Minify to remove comments and compress whitespace for the smallest possible bundle size.
  • Toggle between 2 spaces, 4 spaces, or Tab indentation using the options next to the output.
  • Use Load Sample to paste a complete ES6+ class example and see the formatter in action.

What this is for

Minified or auto-generated JavaScript is nearly impossible to read or debug. This tool restores proper indentation and line breaks so you can inspect logic, trace bugs, and understand unfamiliar code. The built-in validator catches syntax errors using the browser runtime before you copy the result. When the code is ready, minify it to cut load times in production.
