CSS formatter

What it does

The Carbide CSS formatter turns cramped or minified stylesheets into clean, consistently indented CSS that is easy to read and maintain, and can minify them back into the smallest compact form when you are ready to ship. It is free, runs fully in your browser, and is offline-friendly after the first load, so your styles stay private and are never uploaded anywhere. Paste a single rule or an entire stylesheet into the editor, choose beautify to get tidy selectors, properties, and spacing, or minify to strip comments and collapse whitespace for production. Live syntax highlighting makes it easy to spot selectors and values as you work, and the minifier carefully preserves the contents of string literals such as content values so nothing breaks. The CSS formatter is ideal for cleaning up exported or generated styles, reviewing a colleague's code, debugging specificity, or quickly shrinking a stylesheet, giving you well-structured CSS in a couple of clicks with copy and download built in.

How to use the CSS formatter

1. Paste or type your CSS into the editor
2. Choose beautify for clean, indented rules
3. Or choose minify to compress the stylesheet
4. Scan the result with live syntax highlighting
5. Copy the CSS or download it as a .css file

Frequently asked questions

Is the CSS formatter free?

Yes, completely. There is no sign-up, no watermark, and no cap on how many stylesheets you can format or minify.

Does the tool send my CSS to a server?

No. All formatting and minifying runs on-device in your browser, so your stylesheets never leave your computer and work offline once the page has loaded.

Can it minify CSS as well as beautify it?

Yes. Use beautify for readable, indented CSS or minify to remove comments and insignificant whitespace for the smallest production file.

Will minifying change how my styles render?

No. Minifying only removes comments and unnecessary whitespace; it preserves string contents such as content values, so the rendered result is unchanged.
