How to Beautify or Minify CSS
The CSS Beautifier formats compressed or messy stylesheets into clean, readable code — or minifies them for production.
- Paste your CSS into the editor.
- Click Beautify to add indentation and line breaks, or Minify to compress.
- Copy the formatted result or download it.
Why Format CSS?
Readable CSS with consistent indentation makes debugging layout issues far easier. Minified CSS removes whitespace, comments, and unnecessary semicolons to reduce file size — typically by 15–40%. Build tools like PostCSS handle this in production, but this tool is perfect for quick one-off formatting tasks.
Why Use Our CSS Beautifier?
- Beautify and minify — both directions in one tool.
- Customizable indent — 2 spaces, 4 spaces, or tabs.
- Handles modern CSS — supports nesting, custom properties, and @layer.
- No server — runs entirely in your browser.
Frequently Asked Questions
Does it support SCSS or Less?
The tool formats standard CSS. SCSS and Less syntax may work for simple cases, but nesting and variables specific to those preprocessors are not guaranteed to parse correctly.
Will minifying CSS break my styles?
No. Minification only removes whitespace and comments. It does not alter selectors, properties, or values.
Can it sort CSS properties?
Currently the tool preserves property order. Sorting (alphabetical or by type) is a potential future feature.
Is my CSS private?
Yes. All processing happens in your browser.
