Strings,
url(...), and quoted values are preserved.Introduction à l'outil
Compress CSS to its smallest equivalent form by removing comments, collapsing whitespace, and stripping the trailing semicolon before each closing brace.
Vue d'ensemble de l'outil
CSS minification removes characters the browser does not need to render styles correctly. This tool strips /* ... */ comments, collapses runs of whitespace outside of strings, and removes whitespace around structural punctuation ({ } : ; , >). Strings inside url(...) and quoted values are preserved exactly. Byte counts before and after are reported so you can see the savings at a glance. Everything runs in your browser.
Cas d'usage
- Inline critical CSS into <head> with the minimum possible bytes.
- Quickly compress hand-written CSS without spinning up a build pipeline.
- Squeeze additional bytes out of stylesheets already processed by Tailwind or PostCSS.

Will minification break url() values or strings?+
No. Quoted strings and url() contents are preserved verbatim — only the surrounding CSS is compressed.
Does it support nested CSS or @media blocks?+
Yes. Brace-balanced rules of any depth are minified safely; @media, @supports, and nested selectors round-trip correctly.
Will it rename selectors or shorten colors?+
No. The minifier only removes characters that do not affect output. It does not rewrite selectors or convert color formats.
