About This Tool


JavaScript minification reduces file size by removing unnecessary characters. This speeds up downloads and improves page load times.

Our minifier removes whitespace, line breaks, and comments from your JavaScript code. It handles modern ES6+ syntax including arrow functions, template literals, and classes.

Unlike advanced minifiers, we focus on safe compression that won't break your code. Variable names are not shortened, ensuring your minified code remains debuggable if needed.

For production sites, JavaScript minification is essential. Combined with gzip compression on your server, you can achieve significant bandwidth savings.

FAQ

Is the minified code safe to use?
Yes, we only remove whitespace and comments. Your code logic is unchanged.
Does it shorten variable names?
This basic minifier does not rename variables. For that, use tools like Terser or UglifyJS.
Will it work with React/Vue/Angular?
Yes, the minifier handles modern JavaScript syntax used by these frameworks.
Should I minify node_modules?
No, libraries should be minified by their authors. Focus on your own code.
Does minification affect debugging?
Minified code is harder to debug. Keep source maps or original files for development.
