About the CSS Minifier Engine
Unoptimized CSS files are full of comments, indentation, and spaces that make the code readable for humans but add unnecessary weight to the file. The OnlinePaste.com CSS Minifier uses advanced Regex patterns to safely strip this bloat, producing a highly optimized stylesheet for production environments.
Improve Core Web Vitals
Search engines like Google heavily factor page load speed into their ranking algorithms. By minifying your CSS, you decrease the First Contentful Paint (FCP) and Time to Interactive (TTI) metrics. Our real-time Compression Stats Engine shows you exactly how many bytes of bandwidth you are saving before you deploy.
CSS Beautifier Included
Did you lose your original stylesheet and only have the minified version available? Click the Beautify / Format button. Our tool can reverse-engineer minified code, automatically injecting line breaks and standard 2-space indentation to make the code human-readable again.
