CSS Beautifier

CSS Beautifier takes minified or messy CSS and reformats it into clean, properly indented code you can actually read. It's completely free to use and requires no sign-up, so you can beautify stylesheets the moment you need them. Front-end developers, students learning CSS, and anyone debugging a third-party stylesheet will find this tool especially handy.

Why use a CSS Beautifier?

Minified CSS strips out whitespace, line breaks, and comments to save bytes, which makes it nearly impossible for a human to scan through. This tool reinserts consistent indentation, places each selector and declaration on its own line, and preserves the original property order so the logic of your stylesheet stays intact. Whether you're reverse-engineering a competitor's site or reviewing a teammate's pull request, readable CSS speeds up every step of the process.

How to use CSS Beautifier

1. Paste your minified or compressed CSS into the input box.
2. Click the beautify button to instantly reformat the code.
3. Copy the formatted CSS or download it for use in your project.

Frequently asked questions

Is CSS Beautifier free?

Yes, CSS Beautifier is completely free with no sign-up or subscription required. You can beautify as many stylesheets as you need without hitting a paywall.

Does it change how my CSS behaves?

No, formatting only affects whitespace and indentation, not the actual rules or values. Your selectors, properties, and cascade order remain exactly as you wrote them.

Can it handle SCSS or LESS files?

This tool is built for standard CSS syntax rather than preprocessor-specific features like variables or mixins. For best results, compile SCSS or LESS to plain CSS first, then beautify the output.

Will beautifying increase my file size?

Yes, adding back whitespace and line breaks increases the file size compared to the minified version. That's expected — beautified CSS is meant for development and debugging, so minify again with the CSS Minifier before deploying.
