CSS Beautifier Online — Format, Indent & Minify CSS
Paste raw CSS and get perfectly formatted, indented, and readable code in seconds. This tool also provides minification for production builds. Everything runs in your browser, so your code stays private.
Why Use a CSS Beautifier?
Clean, consistent CSS increases developer productivity, reduces bugs, and simplifies maintenance. When CSS is minified for production it becomes compact but hard to read. A beautifier reverses that process for human review, while minification prepares code for deployment. Using both tools as part of a workflow ensures high quality and fast delivery.
Common Scenarios
- Reformatting third party CSS for debugging
- Preparing CSS for code reviews
- Converting minified CSS back to readable form
- Cleaning up exported CSS from design tools
- Minifying CSS for production performance
How the Beautifier Works
The tool normalizes spacing, inserts line breaks, and indents rules and properties based on nesting level. It also keeps comments intact by default and offers options to remove comments when minifying.
Best Practices
- Keep source files readable for development using the beautifier
- Use minified files in production to reduce payload size
- Maintain consistent style guide for selectors and properties
- Run a linter in CI for enforcement of conventions
