CSS Formatter beautifies disorganized or concatenated CSS into consistently indented, rule-by-rule output — and minifies production stylesheets by stripping whitespace, comments, and redundant semicolons to reduce file size. CSS from third-party libraries, build tool output, or legacy codebases is often minified into a single line or formatted inconsistently across contributors. The beautifier makes stylesheets readable for auditing and modification; the minifier removes every unnecessary byte for production performance. All processing runs client-side in your browser, so you can safely paste internal stylesheets containing proprietary class names, unreleased design tokens, or brand-specific variables.

Simply input your data into the fields above. Our CSS Formatter will process your information instantly. You can then copy the results or export them depending on the specific tool features like Beautify or Minify.
