Frequently Asked Questions
Why should I minify my CSS?
Minifying CSS reduces the file size, which means the browser can download and parse it faster. This improves your website's loading speed and user experience.
Is it safe to use this tool?
Yes, completely. The tool runs entirely in your browser using JavaScript. Your code is never uploaded to any server.
Will minification break my CSS?
No, minification only removes unnecessary characters (like spaces and comments) that are not required for the browser to understand the code. The functionality remains exactly the same.
