CSS Minifier

Remove whitespace and comments from CSS to reduce file size.

CSS minification removes all unnecessary characters from your stylesheet — whitespace, comments, line breaks and redundant semicolons — without changing how it works. The result is a smaller file that loads faster in the browser, improving your site's performance and Google PageSpeed score. Even a modest reduction in CSS file size can meaningfully improve load times, especially on mobile connections.

How to use:

• 1. Paste your CSS into the input box on the left
• 2. Click Minify
• 3. See the original size, minified size and percentage saved
• 4. Copy the minified CSS to use in production
