Pretty-print your CSS stylesheets with consistent indentation and one property per line for maximum readability.
The CSS Formatter is a free browser-based tool that takes minified or messy CSS and restructures it with proper indentation, placing each selector on its own line, opening braces after selectors, each property-value pair on a separate line, and closing braces aligned with their selectors. The result is clean, maintainable code that's easy to scan and edit.
Reading minified CSS is a common pain point when debugging production issues or reviewing third-party themes and frameworks. This formatter instantly restores structure so you can identify selectors, spot conflicts, and understand specificity without squinting at a wall of compressed text.
Paste your CSS, set your preferred indent size, and click format. Everything runs locally in your browser with zero data sent to external servers. The formatted output is ready to copy and use in your editor, code review, or documentation.
This tool handles any valid CSS including nested media queries, keyframe animations, and complex selectors. It's the quickest way to go from unreadable minified styles to a well-organized stylesheet without installing any extensions or build tools.
