CSS Beautifier & Formatter

About this tool

Beautify and format CSS code with our free online CSS beautifier tool. Transform minified, compressed, or poorly formatted CSS into clean, readable, properly indented code. Perfect for debugging minified CSS files, understanding third-party stylesheets, cleaning up messy code, preparing CSS for editing, code review readability, learning from minified frameworks, or maintaining consistent CSS formatting across projects.

Our CSS beautifier intelligently formats your code with proper indentation, adds line breaks after rules and selectors, spaces property values appropriately, organizes nested rules, and maintains proper CSS syntax. Customizable formatting options let you control indentation style (spaces or tabs), spacing around selectors and properties, empty line handling, and more to match your coding standards or team conventions.

Essential for web developers debugging minified production CSS, designers customizing third-party themes, students learning from compressed framework CSS, code reviewers needing readable stylesheets, teams maintaining coding standards, and anyone needing to make CSS code more readable. The tool handles CSS3, vendor prefixes, media queries, keyframe animations, and all modern CSS features.

All formatting happens instantly and securely in your browser - your CSS code stays completely private with no server uploads. No registration required, no file size limits, works on mobile devices, and functions offline. Free to use unlimited times for all your CSS formatting needs.
