JavaScript Minifier & Formatter

Minify or pretty-print your JavaScript code instantly.

How does it work?

Minified JavaScript weighs less and makes your pages faster. Formatting it, on the other hand, is essential to keep code readable.

The tool removes comments and unnecessary whitespace while respecting strings (including template literals with backticks), and lets you copy the final result.

Frequently asked questions

Do strings break when minifying?

No: the process recognizes single quotes, double quotes and template literals, and preserves their exact content without touching internal whitespace.

Does it remove comments?

Yes, both line comments (//) and block comments (/* */), because they do not affect execution and take up unnecessary space in production.

Does this minifier replace build tools?

For quick jobs, yes. For large projects it is better to use bundlers with minification (Terser, esbuild or Next.js itself) that also rename variables.
