What is a CSS beautifier online?

A CSS beautifier (CSS formatter) takes minified or unstructured CSS and adds proper indentation, line breaks between properties, and consistent formatting — making stylesheets readable and maintainable.

Is this CSS code minifier free?

Yes — 100% free, no signup. This tool works both as a CSS beautifier and CSS minifier. Minify mode removes all whitespace to reduce file size for production.

Does this CSS beautifier upload my code?

No. All formatting happens in your browser. Your CSS code is never uploaded to any server — safe for proprietary stylesheets.

Can I use this to format SCSS or Sass?

This tool is optimized for standard CSS. For SCSS/Sass, the beautification may work partially since SCSS is a superset of CSS, but nested rules may not format perfectly.
