CSS Formatter parses and pretty-prints CSS rules with consistent indentation and spacing — or minifies them to a single line. Works entirely in your browser with no server required.
body {
margin: 0;
padding: 0;
font-family: sans-serif;
}
.container {
max-width: 1200px;
margin: 0 auto;
}No — this tool handles plain CSS only. SCSS and Less use preprocessor syntax (variables, nesting, mixins) that plain CSS parsers don't understand.
Yes — all formatting and minification happens locally in your browser. Your CSS is never sent to a server.
Formatting (pretty-print) adds consistent indentation and line breaks for readability. Minifying removes all unnecessary whitespace, comments, and line breaks to produce the smallest possible file size.
No — minification only removes whitespace, comments, and redundant characters. The actual selectors, properties, and values remain functionally identical.
Both work — paste anything from a single rule to a full stylesheet with multiple rules, media queries, and nested at-rules.
Basic structural issues like mismatched braces are flagged. It is not a full CSS validator and won't catch invalid property names or values.
Minified CSS is smaller, which reduces page load time. Most build tools do this automatically, but this tool is useful for quick one-off snippets or manual workflows.
