CSS Beautifier
Turn a wall of minified CSS into something you can read and edit. Paste CSS to put every rule and declaration on its own line with consistent indentation — ideal for inspecting a site's styles, fixing a theme, or cleaning up generated CSS.
Paste CSS, pick 2 spaces, 4 spaces or tabs, and click Beautify. Each selector, declaration and closing brace goes on its own line and nested at-rules like @media are indented. Copy or download the formatted stylesheet.

Readable CSS
Formatted CSS makes it easy to find the rule that sets a colour, compare breakpoints in media queries, or spot duplicated declarations. When you're done editing, minify it again for production with the CSS Minifier.

Frequently Asked Questions
Does it support SCSS or Less?
It formats plain CSS and handles most SCSS/Less syntax reasonably, but it's not a dedicated preprocessor formatter.
Is my code or data uploaded?
No. Everything runs in your browser; nothing you paste is sent to a server or stored.
