💡
Beautify formats compressed or minified CSS into readable code with proper indentation and line breaks — great for debugging or reading third-party stylesheets. Minify strips comments and whitespace to reduce file size for production deployments. Neither mode modifies property values.

What is CSS Formatter & Minifier?

CSS Formatter & Minifier helps you switch between readable stylesheet code and compact production-ready output. It is useful for debugging compiled CSS, reviewing selectors and declarations, and compressing styles again before shipping them.

  1. Paste the CSS you want to beautify or compress.
  2. Choose format or minify mode and adjust indentation if needed.
  3. Review the output for readability or file size reduction.
  4. Copy the result back into your stylesheet or build pipeline.

Frequently Asked Questions
Does formatting change the behavior of my CSS?

No. Adding whitespace and line breaks to CSS has no effect on how browsers parse and apply the styles. The formatted output is functionally identical to the original.

Can I format CSS that includes vendor prefixes?

Yes. Vendor-prefixed properties like -webkit-transform or -moz-appearance are treated as standard properties and formatted normally.

Does it handle SCSS or Less syntax?

The formatter is optimized for standard CSS. SCSS/Less-specific syntax like nesting or variables may not format correctly; use a dedicated SCSS/Less formatter for those files.

Should I format CSS before using it in production?

No. In production you should minify CSS to reduce file size. Use the CSS Formatter during development and code review, then minify before deploying.
