How It Works
Paste Your CSS
Paste your CSS code in the input area. You can paste minified CSS to beautify it, or formatted CSS to minify it.

Tips & Best Practices
Beautify for Development
Use Beautify mode during development for readable code, then switch to Minify for production builds.
Check Size Savings
Use the size analytics to see exactly how much bandwidth you'll save by minifying your CSS.
Media Queries
The formatter handles media queries and nested rules. Complex preprocessor syntax (SCSS/LESS) may need compilation first.
