CSS Formatter
Minify or beautify CSS with size comparison — free, private, no upload required.
About this tool
The CSS Formatter minifies or beautifies your stylesheets directly in the browser using regex-based processing. Paste CSS or upload a .css file to instantly strip comments and whitespace (minify) or reformat with consistent 2-space indentation (beautify). Size savings are shown in real time. Because this uses simple pattern matching rather than a full CSS parser, it won't restructure selectors or optimize values — but it handles the bulk of whitespace reduction with zero dependencies and no server round-trip.
