CSS Minifier

Strip all comments and unnecessary whitespace from your CSS to produce compact, production-ready code. The tool shows original size, minified size, and bytes saved. Minified CSS loads faster, scores better on performance audits, and is parsed identically to the original by every browser.

All processing happens in your browser. No data is sent to any server.

Frequently Asked Questions

What does CSS minification remove?
Block comments (/* … */), excess whitespace and newlines, spaces around structural characters like : ; { }, and the trailing semicolon before a closing brace.
Is minified CSS still valid and functionally identical?
Yes. Minified CSS is parsed and applied identically by any browser. The visual result is exactly the same.
Should I minify CSS in production?
Yes. Minified CSS reduces file size and improves page load speed, which positively affects Core Web Vitals and search rankings.
