CSS Minifier
Paste your CSS code below to compress rules and eliminate unused whitespace.
Why Minify CSS?
CSS files control the visual appearance of your website. Unminified CSS includes comments, indentation, and formatting that make it readable for developers but add unnecessary bytes to the file. Minification removes all of this extra data.
Faster CSS loading means your pages render quicker, reducing the time users wait to see content. This improves Core Web Vitals scores, which are a direct Google ranking factor. Every millisecond counts for user experience and SEO.
How CSS Minification Works
Our CSS minifier uses clean-css, an industry-standard compression tool. It removes whitespace, comments, semicolons, and unnecessary characters. It also merges duplicate rules, removes redundant properties, and shortens color values.
The optimized CSS produces the same visual output as the original but with a significantly smaller file size. This is essential for production websites where every byte of bandwidth matters.
