Free CSS Minifier Tool
Compress your CSS files instantly to reduce loading times and improve your website's performance. This tool removes unnecessary whitespace, comments, and line breaks from your CSS code.
How to Use It
Paste your CSS into the input box and click minify — the tool instantly strips whitespace, comments, and line breaks and gives you a compact output to copy.
Example
body { color: red; } (with formatting and comments) minifies down tobody{color:red} — smaller file size, same visual result.
Common Use Cases
- Reducing CSS file size before deploying to production.
- Speeding up page load times by cutting unnecessary bytes.
FAQs
Will minifying break my CSS?
No — minification only removes whitespace, comments, and line breaks; it doesn't change what the CSS actually does.
