What is CSS Beautify & Minify?

CSS beautification helps developers read and maintain code with proper formatting and indentation, while minification reduces file size by removing unnecessary whitespace and characters for faster page loads. This tool processes everything locally in your browser — your CSS is never uploaded to any server.

Key Features

  • Beautify: Format CSS with proper indentation and line breaks
  • Minify: Remove whitespace, comments, and optimize for production
  • Validation: Detect syntax errors like missing braces or semicolons
  • Sort Properties: Alphabetically organize CSS properties for consistency
  • Color Optimization: Shorten hex codes (#ffffff → #fff)
  • Compression Levels: Normal or aggressive minification
  • Media Query Sorting: Organize breakpoints from small to large
