Transform minified or messy CSS into clean readable code — or compress it for production — instantly in your browser.
Writing clean, maintainable CSS is essential for any web project. But copying CSS from browser dev tools, third-party libraries, or minified production builds often gives you code that's impossible to read. Our CSS Formatter instantly transforms minified or messy CSS into beautifully indented, organized code — and can minify it right back for production use.
Everything runs in your browser. No CSS is ever sent to a server, making it safe to use with proprietary or sensitive stylesheets.
Prettifying adds proper indentation, line breaks, and spacing to make CSS human-readable. Minifying removes all whitespace, comments, and unnecessary characters to reduce file size — typically cutting CSS files by 20–40%.
Yes. All CSS comments (/* comment */) are stripped during minification since they add no functional value to the stylesheet in production.
Extract the CSS content from between the style tags, format it here, then paste it back. The formatter works on pure CSS only.
There is no hard limit. The tool processes entirely in your browser, so performance depends on your device's memory. Stylesheets up to several megabytes process instantly on most devices.
The formatter is optimized for standard CSS. SCSS and LESS files may partially format correctly if they use standard CSS syntax, but preprocessor-specific syntax like variables and mixins may not be handled perfectly.
All processing happens locally in your browser. We never see, store, or transmit your data. This tool is fully client-side and secure.
