Production tips

πŸš€

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

πŸ“¦

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

πŸ’‘

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.
