CSS Minifier by DevHackes strips whitespace, comments, and unnecessary characters from your stylesheets to shrink file size and speed up page loads — without touching how your site looks. Paste your CSS or upload a file, hit minify, and get a production-ready, compressed file in seconds. Works entirely in your browser (nothing uploaded to a server), preserves media queries and keyframes, and shows exactly how many bytes you saved. No signup, no limits.
