Copy and paste your CSS code into the input field.
Click Minify to compress the CSS.
Click Copy to save the minified CSS to your clipboard.
A CSS minifier shrinks your stylesheet by stripping everything the browser does not need: comments, line breaks, indentation, and redundant characters. The rules behave identically; the file just gets smaller and downloads faster.
Minification typically cuts CSS size by 20 to 40 percent before compression, which translates directly into faster first paint on slow connections. Paste your CSS, get the minified version instantly, and ship the smaller file.
CSS blocks rendering: the browser will not paint the page until stylesheets are downloaded and parsed. Every kilobyte trimmed from CSS shortens the blank-screen time, especially on mobile networks. Minification is the cheapest optimization available because it costs nothing in code quality; you keep the readable source and ship the compact build.
Servers usually compress responses with gzip or brotli, and some assume that makes minification pointless. In practice they stack: minification removes characters compression must otherwise encode, and the combination is reliably smaller than either alone. Minify first, then let the server compress the result.
Never edit minified CSS. Keep your formatted, commented stylesheet as the source of truth, and minify as a build step or with this tool before deploying. When you need to debug shipped CSS, paste it into the CSS beautifier to restore readable formatting in seconds.
