Minify CSS for Production Deployment

CSS minification typically saves 20–40% on file size by removing comments, whitespace, and redundant semicolons — zero impact on functionality.

Minified CSS is the standard for production builds. Tools like webpack, Vite, and Parcel do this automatically, but this tool works for any file.

For small projects without a build pipeline, manually minify your CSS before deployment. Even a few KB saved improves Core Web Vitals scores.

The reduction percentage shown tells you how much bandwidth you save on every page load. For high-traffic sites, this compounds significantly.
