About CSS Beautifier

This beautifier reformats minified or messy CSS with one declaration per line, consistent indentation and a space after each colon. Nested blocks such as @media rules are indented one level deeper, and a blank line separates top-level rules.

When it helps

  • Reading a minified stylesheet from a production site or a third-party library.
  • Cleaning up CSS copied from browser DevTools or generated by a design tool.
  • Normalizing inconsistent formatting before a code review.

Tips

  • Choose 2 spaces, 4 spaces or tabs to match your codebase.
  • A missing final semicolon is added before each closing brace, which makes later edits less error-prone.
  • Comments are kept. Strings, including url() paths and content values, are not altered.
  • To shrink the file again after editing, run it through the CSS Minifier.

No. Selectors, properties and values stay in the same order with the same content. Only whitespace and the trailing semicolon change.

Yes. There is no sign-up, no watermark and no limit on how many files you process.

No. Files are read and processed locally in your browser, so they never leave your device.
