Minify or beautify JavaScript code. Remove comments and whitespace for production.
JS minification removes all unnecessary characters: comments (// and /* */), whitespace, newlines, and reduces code formatting while preserving functionality. This reduces file size typically 30-60%, resulting in faster downloads and page loads.
This basic minifier removes comments and whitespace but does not rename variables (that's called "mangling"). For production use with variable renaming, use tools like Terser, UglifyJS, or esbuild which can achieve even smaller output.
Yes. Minification only removes formatting characters that JavaScript ignores during execution. The logic, variables, and behavior remain identical. Always test your minified code to be safe.
This tool works with standard JavaScript. TypeScript and JSX need to be compiled to JS first (using tsc or Babel) before minification. The resulting JS can then be minified here.
