Quick Answer
A CSS beautifier re-indents stylesheets so every rule is on its own line and nested blocks are easy to follow. If you have ever opened a minified .css file and seen one giant line, this tool turns it back into something a human can actually read.
What This Tool Does
The beautifier tokenizes your CSS, tracks brace depth, and re-emits each rule and property on its own line with consistent indentation. Strings, comments and values are preserved exactly — only the whitespace layout changes.
Key Features
- Instant re-indentation — paste and read; no configuration needed.
- Brace-depth aware — media queries, keyframes and nesting indent correctly.
- Preserves comments — your
/* notes */stay intact. - Copy or download the beautified stylesheet.
How to Use the CSS Beautifier
- Paste your minified CSS into the input box.
- Read the formatted result on the right — it updates live as you type.
- Click Copy to grab it, or Download to save the file.
Use Cases
- Reading a stylesheet that came from a CSS framework’s minified build.
- Debugging a selector by being able to see where its properties begin and end.
- Reviewing third-party CSS before deciding to vendor it.
Tips
- Beautified CSS is for humans; minified CSS is for the wire. Keep both versions.
- Check that custom properties (
--name) andcalc()expressions survived intact after formatting — the tool preserves values, but a quick skim never hurts.
Privacy
Formatting happens locally. Your CSS never leaves the browser.
Conclusion
Minified CSS is great for performance and terrible for reading. This beautifier gives you the readable version in one paste — free and private.
