Beautify and minify CSS, HTML, JS code
What is Code Beautifier?
Code Beautifier formats and minifies CSS, HTML, and JavaScript code with configurable indentation and style rules.
When to use this tool
- Cleaning up minified or auto-generated CSS/HTML/JS
- Standardizing code style before committing
- Reducing file size for production by minifying
- Making code readable for debugging
How it works
Parses source code into an AST (Abstract Syntax Tree) and re-serializes it with consistent formatting: indentation, line breaks, quote style, and trailing semicolons. Minification removes whitespace and shortens variable names where safe.
