Minify CSS code to reduce file size
CSS minification is the process of removing unnecessary characters from CSS code without changing its functionality. This includes whitespace, line breaks, comments, and redundant semicolons. Minified CSS files are smaller, which means faster download times and better page load performance for your website visitors. Our CSS Minifier processes your code instantly and shows you exactly how much space was saved.
Smaller CSS files directly improve Core Web Vitals metrics like Largest Contentful Paint (LCP) and First Contentful Paint (FCP), which are factors in Google's search rankings. This tool is ideal for developers who want to quickly minify CSS before deploying to production. Paste your CSS, click minify, and copy the optimized output. All processing happens locally in your browser — your code is never sent to any external server.
