Beautify and minify CSS stylesheets
About CSS Formatter
How CSS Formatter Works
Paste a stylesheet and it is expanded for editing or minified for production in your browser. All formatting runs client-side, so your CSS never leaves your device.
The CSS Formatter reformats stylesheets into clean, readable rules and can also minify them for production. A typical use case is expanding a compressed vendor stylesheet so you can understand it, or collapsing your own CSS to shrink the file served to users. The tool runs in the browser, so your styles never leave the page. Consistent formatting makes cascade conflicts and duplicate selectors easier to spot, and minification reduces bandwidth on slow connections. It is a quick way to enforce a tidy style without installing a build plugin, and it helps when auditing a large stylesheet for unused or conflicting rules.
Frequently asked questions
Can it minify as well as beautify?+
Yes. You can expand for editing or compress for production.
Is my CSS uploaded?+
No. All formatting happens locally in your browser.
Does it fix bad selectors?+
No. It only reformats whitespace, not the rules themselves.
Limitations
It does not autoprefix or rewrite properties for browser compatibility. Minified output is harder to read.
