CSS Minifier
Minify and compress CSS by removing comments, whitespace, and unnecessary characters.
What is CSS Minification?
CSS minification strips all whitespace, comments, and redundant characters from a stylesheet while preserving its full functionality. The browser interprets minified CSS identically to the original — it's purely a size reduction for faster delivery.
On large stylesheets, minification typically reduces size by 20–50%. Combined with gzip compression on the server, the savings are even greater. Most build tools (Webpack, Vite, Parcel) include CSS minification automatically for production builds.
How to Use
Paste your CSS into the input panel and click Min. The output shows the fully minified CSS on a single line. The savings indicator shows how many characters were removed as a percentage.
