β¨ CSS Beautifier
Turn minified CSS into clean, readable code instantly.
How to Use This Beautifier
Paste any CSS, minified or messy, choose your indent style, and get consistently formatted output. Use it to inspect third-party stylesheets, clean up generated code, or standardize formatting before a code review. All processing happens in your browser; nothing is uploaded.
Paste CSS into the input box.
Choose indent size and brace style.
Click Beautify, then copy the formatted output.
What Beautifying Does
The formatter parses your CSS into rules and declarations, then re-emits each on its own line with consistent indentation. Selectors stay on one line, each property gets its own line, and braces follow your chosen style. It also normalizes spacing around colons and combinators, and optionally ensures every declaration ends with a semicolon, which prevents subtle bugs when rules are concatenated.
Comments are preserved in place. At-rules like @media get their nested rules indented one extra level, making responsive code dramatically easier to scan. The beautifier does not change specificity, order, or values: formatting is purely cosmetic, so output is safe to ship.
When to Beautify vs Minify
Beautify during development and debugging: reading minified CSS in DevTools is painful, and pasting a library's stylesheet here reveals its structure instantly. Minify for production with our CSS Minifier: smaller files download faster. A healthy workflow keeps beautified source in version control and ships minified builds automatically.
Formatting Style Guide
This expanded style (brace on the same line, 4-space indent, one property per line) is the most common convention and the default here. Compact style puts each rule on fewer lines but hurts scannability. Whatever you choose, apply it consistently: mixed formatting in one codebase slows every reader down.
Limitations
This is a formatter, not a validator: it will not fix broken CSS, though malformed input usually still formats without crashing. Very exotic syntax (some CSS-in-JS template literals, preprocessor nesting with & in odd positions) may format imperfectly. For SCSS or Less sources, compile to CSS first, then beautify.
Frequently Asked Questions
What does a CSS beautifier do?
It reformats minified or inconsistently styled CSS into clean, indented, human-readable code. Each selector and property gets its own line with consistent spacing. It changes formatting only, never the actual styles.
Is beautified CSS safe to use in production?
Yes, formatting does not change how CSS works. But for production, minified CSS is better because smaller files load faster. Beautify for reading and debugging, minify for shipping.
Can I beautify SCSS or Less?
Not directly. Compile preprocessors to plain CSS first, then paste the output here. The formatter handles standard CSS including @media queries and keyframes.
What indent style should I use?
Match your project's existing convention. 2 spaces is common in modern codebases, 4 spaces in traditional ones, tabs for accessibility (they respect user tab-width settings). Consistency matters more than the choice.
Does it preserve comments?
Yes, comments are kept in place. The formatter only adjusts whitespace and line breaks around rules, declarations, and braces.
