Frequently Asked Questions

Why would I want to minify my CSS?
Minified CSS reduces the number of bytes transferred over the network. Every byte saved means faster page load times, lower bandwidth costs, and improved Core Web Vitals scores. A typical CSS file can be reduced by 30-60% through minification, with further savings when GZIP compression is applied by the server.
Will minification break my styles?
This tool only removes whitespace and comments — it does not reorder rules, change selectors, or modify values. The computed styles produced by the minified CSS are identical to the original.
Is my code sent to a server?
No. Minification runs entirely in your browser. Nothing is transmitted.
