Format or minify CSS online with support for indentation selection, responsive media query examples, and result duplication. Styles are only processed as text and are not injected into the current web page or loaded from external resources.
Compression may normalize equivalent writing; the result will not be directly injected into the site's styles. Please verify the style on the landing page.
72 / 100,000 characters
Shortcut key: Ctrl/⌘+Enter. Modifying inputs or options clears old results.
The compression mode may merge or normalize equivalent writing methods, and there is no guarantee that the output will only differ from the original text by whitespace.
This page is parsed by CSS, not the Sass/Less compiler. Please compile the preprocessor syntax in the project first.
Formatting is done through Prettier parsing CSS, and compression is done through CSSO. Typesetting and compression will not verify whether the style is rendered correctly on your page. You should check it on the target page after making changes.
