About this tool

CSS files often contain whitespace, comments, and formatting added for readability. In production, these add unnecessary bytes to every page load. Minifying CSS removes all comments and excess whitespace without changing the behaviour of the styles, reducing file size by 20–50% in typical cases. This tool performs client-side minification without any server round-trip.
