What is a CSS beautifier?

The CSS Beautifier formats minified, compressed, or poorly formatted CSS code into clean, readable, properly indented code. It adds consistent spacing, newlines, and indentation to make CSS easy to read, edit, and understand.

Minified CSS is great for production but impossible to edit directly. When you need to inspect, debug, or modify minified CSS from a production site or third-party source, the beautifier transforms it into readable, editable code in seconds.

Why use a CSS beautifier?

Receiving or inheriting minified CSS is common in web development — from CDN-hosted libraries, CMS themes, or production deployments. Beautifying minified CSS makes it immediately readable and editable, saving the time and mental effort of parsing compressed code manually.

CSS beautifier: frequently asked questions

Something else? Ask the team

What is the difference between beautifying and minifying CSS?

Minifying removes all formatting to reduce file size for production. Beautifying adds proper formatting for readability during development. They're opposite operations with different use cases.

Can I set the indentation style?

The default indentation is 2 spaces. Options for 4-space indentation or tab indentation are available to match your team's code style.

Will beautification change my CSS selectors or values?

No. The beautifier only adds whitespace and newlines. All CSS selectors, properties, and values remain exactly as they are in the original code.

Can I use this to understand third-party CSS?

Yes. Beautifying minified CSS from external libraries or themes makes it readable so you can understand what styles are applied and find what you need to override.

Does it handle CSS preprocessor output?

It handles standard CSS output. If you have Sass/Less source files, use their respective formatters. Compiled CSS output from preprocessors is valid CSS that this tool can format.
