Verschönern und formatieren Sie CSS-Code sofort mit unserem kostenlosen online CSS Beautifier. Saubere Einrückung, lesbare Struktur und korrekte Formatierung. 100% clientseitig.
CSS Beautifier is a free online tool that transforms messy, minified, or poorly formatted CSS code into clean, readable, and properly indented stylesheets. Whether you inherited a compressed CSS file from a build process, downloaded a third-party stylesheet, or need to clean up your own code, this tool instantly formats it with professional standards. All processing happens entirely in your browser — no data is sent to any server, ensuring your code stays private and secure.
CSS beautification (also called prettification or formatting) is the process of restructuring CSS code to make it readable and consistent. It adds proper indentation, spacing, line breaks, and grouping while preserving the exact styles and functionality.
No. The beautifier only changes whitespace, indentation, and formatting. It does not alter any CSS values, selectors, properties, or media queries. The rendered output in the browser will be identical before and after beautification.
This tool is designed for standard CSS. While it may handle some SCSS features like nesting, variables, and mixins are not supported. For full SCSS/Sass formatting, use a dedicated preprocessor tool like Prettier or the Sass CLI.
Beautifying makes CSS readable by adding indentation, line breaks, and spacing. Minifying does the opposite — it removes all unnecessary whitespace to create the smallest possible file size for production. This tool supports both: click "Beautify" for readability, "Minify" for performance.
Alphabetical property sorting improves code consistency across team members, makes it easier to spot missing properties, and simplifies code reviews. It is a common practice in large CSS codebases and design systems.
Yes, completely. All CSS processing happens inside your browser using JavaScript. No code is sent to any server, stored in any database, or logged anywhere. You can verify this by checking your browser's network tab — no outbound requests are made when you process CSS.
Yes. The beautifier fully supports CSS custom properties (--variable-name), CSS Grid, Flexbox, CSS nesting, container queries, and other modern CSS features. Your cutting-edge CSS code will be formatted correctly.
Yes. After beautifying, click the "Download" button to save your formatted CSS as a .css file with a timestamp in the filename. This makes it easy to keep track of multiple versions.
