Frequently Asked Questions
What does a CSS minifier do?
A CSS minifier removes unnecessary characters from your stylesheet (such as spaces, line breaks, indentation, and comments) without changing how the CSS functions. This results in a much smaller file.
Why should I minify my CSS?
Minified CSS files are smaller, meaning they download faster. This improves your website's loading speed, performance, and can even boost your SEO rankings.
Is my CSS sent to a server?
No. This CSS minifier runs entirely client-side in your web browser. Your code is processed locally and is completely private.
