CSS Formatter — Free Online Tool

Beautify or Minify Your CSS Instantly

Stop struggling with messy or bloated CSS code. Whether you've inherited a legacy stylesheet, generated raw output from a preprocessor, or just need to minify for deployment — ToolMateX’s CSS Formatter helps you do it all.

Customize Indentation Style

Prefer tabs over spaces? Want to match your team’s 4-space standard? ToolMateX lets you choose exactly how your CSS should be indented — tabs or any number of spaces from 1 to 10.

Sort CSS Properties Alphabetically

With one toggle, you can alphabetically order all CSS properties within rule blocks. This is great for style guide compliance, reducing merge conflicts, and scanning for duplicates.

• ✅ Alphabetize properties for consistency
• ✅ Improve maintainability across teams
• ✅ Optional — toggle it on or off anytime
