Free CSS Minifier Online — Minify CSS code to reduce file size
How to Minify CSS
Paste your CSS code and click Minify. The tool removes comments, extra whitespace, and unnecessary characters to reduce file size while keeping the CSS functionally identical.
How much can CSS be compressed?
Typically 20-40% reduction depending on formatting. Well-commented CSS with lots of whitespace sees the biggest savings.
Does minification break CSS?
No. Minification only removes characters that don't affect rendering: comments, extra spaces, newlines, and trailing semicolons before closing braces.
