Why Minify CSS?
Every byte of CSS must be downloaded before the browser can render your page. Minifying CSS removes unnecessary whitespace, comments, and formatting, typically reducing file size by 20–50%. For large stylesheets, this can save hundreds of kilobytes and measurably improve Largest Contentful Paint (LCP).
Google PageSpeed Insights flags unminified CSS as an opportunity. Most production build tools (webpack, Vite, Parcel) minify automatically, but this tool is useful for quick fixes, third-party stylesheets, or simple websites without a build pipeline.
