IconVault's CSS Beautifier turns minified or messy CSS into clean, consistently indented code you can actually read. It parses rules, nested @media queries and declarations properly, protecting strings and comments so braces and semicolons inside them never break the output. An optional alphabetical property sorting mode arranges declarations from A to Z.

You also get honest stats: rule, selector and declaration counts plus before and after sizes, so minified input shows a readable size comparison. Copy the result or download it as a .css file. Free, no signup, and runs fully in your browser, so your stylesheets never leave your device.
