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. You can also switch the mode to Minify to compress the output, or load a stylesheet from a file or URL.
Key Features
- Instant re-indentation — paste and read; no configuration needed.
- Brace-depth aware — media queries, keyframes and nesting indent correctly.
- Beautify or minify — one tool for both readable and compressed output.
- CSS, SCSS and LESS — nested rules,
$variables,@mixinsand&selectors survive intact. - Adjustable indentation — 0 to 10 spaces or tabs, matching your style guide.
- Sort properties alphabetically — tidy declarations in one click.
- Blank line between rules and remove last semicolon options.
- Preserves comments — your
/* notes */stay intact. - Upload file or load from URL — beautify existing stylesheets directly.
- Copy or download the beautified stylesheet.
How to Use the CSS Beautifier
- Paste your minified CSS into the input box, or use Upload File / Load from URL.
- Pick the mode (Beautify or Minify), syntax (CSS, SCSS, LESS) and indentation.
- Open Show advanced options to sort properties, add blank lines between rules, or drop the last semicolon.
- 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.
