What is CSS/JS/HTML Minifier?

Minification removes comments, extra whitespace, and line breaks from code without changing how it runs, reducing file size for faster page loads. Pick a language tab, paste your code, and copy the minified result.

FAQ

Will this break my code?

It's a lightweight, best-effort minifier for simple snippets — for production builds, a dedicated build-tool minifier (like esbuild, Terser, or cssnano) is safer for complex code.

Is my code sent anywhere?

No, minification happens entirely in your browser.
