How it works: Paste minified CSS → click Beautify → get well‑indented, readable CSS with proper line breaks and spacing.

🎯 Why Beautify CSS?

Readable CSS is easier to debug, maintain, and collaborate on. Our beautifier takes compressed CSS (often from build tools or copied from production) and formats it with consistent indentation, spaces after colons, and line breaks between rules. It preserves all style properties while making the code human‑friendly. Perfect for developers who need to understand third‑party CSS or recover lost source formatting. The tool runs entirely in your browser – no data is uploaded.

⚙️ How the Beautifier Works

We use a simple parser: split by `{` and `}`, then reconstruct with proper indentation. It handles nested media queries and keyframes. The algorithm adds a space after `:` and ensures each property is on its own line. The result is consistent, clean CSS.

❓ FAQ

1. Does it support SCSS/SASS?

No, only standard CSS.
