FAQ
Common questions and answers about this topic.
What does CSS minification do?
Removes whitespace, comments, and unnecessary characters from CSS to reduce file size for faster page loading.
Will minification break my CSS?
No, minification only removes formatting without changing the logic. The CSS will render identically in the browser.
How much can file size be reduced?
Typically 20-50% depending on the original formatting and amount of comments.
Is my data sent to any server?
No, CSS minification is performed entirely in your browser. Your stylesheets are processed locally with JavaScript and never transmitted to any server.
