CSS minification removes comments, whitespace, and unnecessary characters from your stylesheets to reduce file size and improve page load speed. This free online CSS minifier instantly compresses your code and shows real-time statistics including original size, output size, and percentage savings. You can also beautify minified CSS back into a readable, indented format for debugging and editing.
Paste your CSS directly, upload a .css file, or drag and drop it into the editor. The side-by-side panel layout lets you compare input and output at a glance, with a resizable divider for comfortable viewing. When you are done, copy the result to your clipboard or download it as a file.
All processing runs in your browser using JavaScript. No CSS is sent to any server, so your code stays private. This tool is built for front-end developers, web designers, and anyone who wants to optimize CSS for production.
