Minify HTML, CSS, and JavaScript code instantly. Remove whitespace, comments, and compress your code for faster page loads and better performance.
<!-- -->Code minification is the process of removing unnecessary characters from source code without changing its functionality. This includes whitespace, line breaks, comments, and sometimes shortening variable names. The result is a smaller file size that downloads faster and reduces page load times.
For HTML, minification removes extra whitespace between tags, strips comments, collapses boolean attributes, and removes optional closing tags. A typical HTML page can be reduced by 10-20% through minification alone.
For CSS, the process removes comments, collapses whitespace, shortens color values (e.g., #ffffff to #fff), removes the last semicolons in declaration blocks, and merges identical selectors. CSS minification typically achieves 15-30% size reduction.
JavaScript minification is the most impactful, removing comments, whitespace, and optionally shortening variable and function names (mangling). Combined with tree-shaking and dead code elimination, JS minification can reduce file sizes by 30-60%.
Google considers page speed a ranking factor, and Core Web Vitals like Largest Contentful Paint (LCP) and First Input Delay (FID) are directly improved by serving minified assets. Every kilobyte saved translates to faster rendering, especially on mobile networks.
