JS / CSS Formatter

How to use

Select the language (JavaScript, CSS, or HTML), paste your code, and click Format to beautify or Minify to compress. Adjust indent size in the options. Copy the result with one click.

Why use this tool

Instantly beautify minified or unformatted code, or compress code for production. No build tools needed — all formatting runs locally in your browser using js-beautify.

FAQ

What languages are supported?

JavaScript, CSS, and HTML are supported for both formatting and minification.

Is my code sent to a server?

No. All formatting uses the js-beautify library running locally in your browser. Your code never leaves your device.

What does minify do?

Minification removes whitespace, comments, and unnecessary characters to reduce file size for production deployment.
