CSS Beautifier - Format & Clean Up CSS Code Online

Free Online CSS Beautifier

The Tooloogle CSS Beautifier rewrites minified or inconsistent CSS into structured, readable stylesheets. Whether you're inspecting a production bundle, cleaning up a Tailwind output, or formatting hand-written rules before commit, the beautifier delivers a consistent, code-review-friendly result.

What It Handles

• Plain CSS (selectors, declarations, media queries)

• SCSS / LESS-style nesting (preserves structure)

• Vendor-prefixed properties (-webkit-, -moz-, etc.)

• CSS variables (--custom-properties) and modern functions (clamp(), min(), color-mix())

Customisation Options

• Indent size — 2, 4, or 8 spaces, or tabs.

• Selector style — one selector per line or comma-grouped.

• Declaration order — preserve original or alphabetise.

• Quote style — single or double quotes around URLs and strings.

• Trailing semicolons — force or remove on the last declaration of each block.

How to Use

1. Paste your CSS (or drop a .css file).

2. Pick your indentation and selector preferences.

3. Click Beautify — the formatted CSS appears instantly.

4. Copy or download the result.

Why Format CSS?

Minified CSS is fast for browsers but painful for humans. A beautified stylesheet makes it easy to find the rule overriding your colour, spot duplicate declarations, debug specificity battles, and identify dead selectors before a refactor. Pair the output with a CSS linter for full code-quality coverage.

Privacy

Formatting runs entirely in your browser. No CSS is uploaded, stored, or logged.
