}A CSS formatter is a developer tool that restructures cascading style sheet code into clean, readable format with consistent indentation, one property per line, and properly nested selectors. When CSS is written inline, generated by preprocessors, or extracted from minified production files, it becomes a dense block that is difficult to read and maintain. This tool parses your CSS and rebuilds it with your choice of 2-space or 4-space indentation, placing each declaration on its own line and properly indenting nested rules like media queries and keyframe animations. In minify mode, it does the reverse — stripping all comments, collapsing whitespace, removing spaces around selectors and properties, and eliminating trailing semicolons before closing braces. The minified output is the smallest valid CSS representation of your stylesheet, reducing bandwidth and improving page load performance. A size comparison shows exactly how many characters and what percentage was saved. All processing runs in your browser with zero server upload, making it safe for proprietary design systems and client stylesheets.
Choose Format to beautify your CSS with clean indentation, or Minify to compress it for production. In format mode, select 2 or 4 space indentation to match your project conventions.
Paste your stylesheet code from your editor, browser DevTools, or build output into the input area. The tool handles selectors, declarations, media queries, and nested rules.
