CSS Beautifier
CSS Beautifier
Paste CSS to format it with consistent brace-based indentation, one declaration per line.
The CSS Beautifier reformats tangled stylesheets into a consistent, readable layout: each rule opens on its own line, every declaration sits on its own indented line, and closing braces line up where you expect them. Styles copied from a minified file, a browser inspector, or an old project usually arrive as an unreadable block; this tool restores order in one click.
The formatter is brace-based: it tracks opening and closing braces to set indentation depth, splits declarations at semicolons, and handles nested blocks such as media queries by indenting their contents a level deeper. Comments are removed during cleanup, so keep your original file if its comments carry notes you need.
Consistent formatting pays off beyond looks. When every rule follows the same pattern, code reviews move faster, teammates can spot the declaration they need without hunting, and version-control diffs show only genuine changes instead of noise created by mixed personal styles across a shared file. It also makes copied third-party snippets safe to paste into a project, because you can read exactly what they do before they go live on your pages.
Your styles are never restyled semantically: selectors, properties, and values come through exactly as written, only the layout changes. The whole job runs in your browser with no upload, so unpublished designs and client stylesheets stay private.

Frequently asked questions
Does it support media queries and nesting?
Yes. Because indentation follows brace depth, rules inside media queries and other nested blocks are indented one extra level automatically.
What happens to comments?
Comments are stripped while formatting to keep the layout logic simple and predictable. If your comments matter, work on a copy of your file.
Will it fix invalid CSS?
No. It formats structure; it does not validate property names or values. Unbalanced braces will produce odd indentation, which often helps you spot the mistake.
Is my CSS uploaded?
Never. Formatting happens locally in your browser.
