About this Tool
Use this free CSS Formatter to turn compressed or inconsistently formatted stylesheets into clean and readable CSS. Paste selectors, declarations, media queries, keyframes, custom properties, or a complete stylesheet, choose an indentation style, and copy or download the formatted result. Processing runs entirely in your browser, so project styles and private source code are not uploaded.
