Why Minify or Format CSS?
Minifying CSS removes all unnecessary characters from the source code without changing its functionality. It strips out whitespace, line breaks, and comments, resulting in a much smaller file size. This significantly improves your website's load speed and Core Web Vitals score.
Formatting (Beautifying) does the exact opposite. If you download a minified CSS file from a production server and need to edit it, our formatter adds proper indentation, line breaks, and spacing, making the code readable for humans again.
CSS Tool FAQ
Is this tool safe for my code?
Yes. The minification process carefully targets only non-essential characters (like spaces and comments) while preserving your actual selectors, properties, and values. Furthermore, everything is processed directly inside your browser. No code is uploaded to our servers.
Will minification break my CSS rules?
No. Standard minification is a mathematically safe operation. However, you should always keep a backup of your original formatted (unminified) code for future development, as editing minified code manually is extremely difficult.
