Minify CSS Online
Compress and minify your CSS code to reduce file size and improve page load speed. Remove comments, whitespace, and optimize selectors.
CSS Minification for Faster Websites
CSS minification is a crucial performance optimization technique that removes unnecessary characters from your stylesheets without changing functionality. This results in smaller file sizes and faster page loads.
What Gets Removed
- Comments: All CSS comments are stripped
- Whitespace: Extra spaces, tabs, and newlines removed
- Semicolons: Last semicolon in blocks removed
- Redundant spaces: Around selectors and properties
Performance Benefits
- Faster downloads: Smaller files transfer quicker
- Reduced bandwidth: Lower hosting costs
- Better Core Web Vitals: Improved FCP and LCP scores
- Lower CDN costs: Less data to cache and serve
- Mobile optimization: Critical for slower connections
When to Minify
Always minify CSS for production. Keep un-minified versions in source control for development and debugging. Use build tools to automate minification in your deployment pipeline. Consider CSS-in-JS or CSS Modules for component-scoped styles.
Additional Optimizations
Beyond minification, consider removing unused CSS with tools like PurgeCSS, using CSS custom properties for repeated values, and implementing critical CSS for above-the-fold content.
