CSS Formatter
Format and beautify CSS stylesheets
About the CSS Formatter
CSS (Cascading Style Sheets) is the cornerstone of web presentation, controlling the visual appearance of every website on the internet. From typography and colors to layouts and animations, CSS transforms raw HTML into beautiful, responsive user interfaces. However, working with CSS from external sources—whether from minified production builds, browser DevTools, or third-party libraries—often results in compressed, unreadable code.
The CSS Formatter on UniversalDevTools.in is a professional-grade online utility engineered to beautify minified CSS into readable, properly indented code, and to minify verbose stylesheets for production deployment. Whether you're debugging inherited legacy styles, reverse-engineering a competitor's design, or preparing CSS for a CDN, this tool transforms any CSS into the format you need.
CSS beautification adds proper line breaks after opening braces, indents properties with consistent spacing, and separates rule blocks for maximum readability. CSS minification does the opposite—stripping all whitespace, comments, and unnecessary characters to reduce file size by 20-40%, improving page load times and Core Web Vitals scores.
Unlike online formatters that send your code to remote servers, this tool processes everything locally in your browser. Your stylesheets—which may contain proprietary design tokens, internal class naming conventions, or client-specific customizations—never leave your device.
