About CSS Formatter

The CSS Formatter beautifies minified or inconsistent CSS into clean, indented rules with one declaration per line, making stylesheets easy to read and maintain. It's ideal for un-minifying production CSS or tidying styles copied from the web. Formatting runs locally in your browser with nothing uploaded. To compress it again for production, use the CSS Minifier, and format markup with the HTML Formatter.

2Adjust any available options to match the result you want.
3Your output is generated instantly — no button-clicking required for most tools.
4Use the Copy or Download button to save your result.

Common Use Cases

Converting between markdown and HTML for docs and CMSs
Cleaning up code snippets for readability

Frequently Asked Questions

Does formatting change my styles?

No. Only whitespace and indentation change. Selectors, properties, and values are preserved exactly, so the formatted CSS behaves identically to the original.

Can it expand minified CSS?

Yes. Paste single-line minified CSS and the formatter breaks it into readable rules with proper spacing and indentation.

Is CSS Formatter free to use?

Yes. CSS Formatter is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use CSS Formatter?

Absolutely. CSS Formatter runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
