Beautify, format and minify JavaScript code instantly. Clean messy JS, fix indentation, compress for production or expand for debugging — 100% free, works in browser.
Paste JavaScript — Copy your messy, minified or unformatted JS and paste it into the input area. You can also press Tab inside the editor.
Choose Mode — Select Beautify to format for development/debugging, or Minify to compress for production use on your live website.
Configure Options — Choose indent size, whether to remove comments, console.log() calls and debugger statements for production-ready minified JS.
Copy or Download — Click Copy to paste into your code editor, or Download to save as .js or .min.js file.
Minification removes all whitespace, comments, line breaks and shortens variable names in JavaScript to reduce file size — typically by 40–70%. Smaller JS files load faster, improving website speed and Google PageSpeed score.
Yes — always serve minified JavaScript on your live website. Keep the original beautified version for development. Most frameworks (React, Vue, Laravel) auto-minify during build. For plain HTML sites, manually minify your JS files.
No — properly minified JS behaves exactly like the original. It only removes characters browsers ignore (whitespace, comments) and optionally renames variables to shorter names. Always test after minifying.
console.log() statements expose internal data to anyone opening browser DevTools on your site. They also slightly slow down performance. Always remove them before deploying to production.
