JS Minifier

Make your JavaScript files lighter. Paste your code to remove comments and extra whitespace for quicker downloads and faster page loads.

How to Use

  1. Paste your JavaScript into the input box.
  2. Click Minify JavaScript.
  3. Copy the compact output for production use.

Key Features

  • Removes comments — strips both line and block comments.
  • Collapses whitespace — code on as few lines as possible.
  • Keeps logic intact — your code runs exactly as before.
  • Size report — see the character and percentage saving.

FAQs

Will minified JavaScript still run?

Yes. Only comments and redundant whitespace are removed; the logic is unchanged.

Can it break code with URLs in strings?

A basic minifier may trim text after // inside strings, so test minified code before deploying it live.

Should I keep the original file?

Always. Keep the readable original for editing and minify a copy for production.

Does it obfuscate my code?

No. Minified code is smaller but still readable; it is not a security measure.
