CSS Minifier

CSS minification removes whitespace, comments, and redundant semicolons from stylesheets to create a smaller, functionally identical file. A typical uncompressed stylesheet may contain hundreds of newlines, indentation spaces, and developer comments that are meaningful to humans but invisible to browsers. Serving minified CSS reduces the number of bytes the browser must download before it can render the page, directly improving render-blocking resource metrics. Tools like cssnano and clean-css power production minifiers; this online tool applies the same transformations in the browser so you can preview results immediately.
