About This Tool


CSS minification is essential for production websites. Our minifier removes all unnecessary characters from your stylesheets while preserving functionality.

Whitespace, line breaks, and comments are removed. Color values are shortened where possible (#ffffff becomes #fff). Zero values lose their units (0px becomes 0).

Redundant semicolons after the last property in a rule are removed. The tool intelligently handles edge cases to ensure your minified CSS works exactly like the original.

The compression ratio is displayed so you can see the impact. CSS typically compresses 20-40% depending on how it was originally formatted.

FAQ

Will minification break my styles?
No, only whitespace and comments are removed. All styles work identically.
Should I keep the original file?
Yes, always keep readable source files. Minified files are for production only.
Does it combine multiple files?
This tool minifies single files. For combining, use a build tool like Webpack.
What about source maps?
This basic minifier does not generate source maps. For that, use a build tool.
Does it remove unused CSS?
No, that requires analyzing your HTML. This tool only minifies existing CSS.
