CSS Formatter
Free online CSS formatter tool, beautify and minify
Why Format CSS?
Well-formatted CSS is easier to read, maintain, and debug. Proper indentation shows the hierarchy of selectors and properties. Minified CSS removes all whitespace for smaller file sizes in production. Consistent formatting also makes code reviews more effective.
How to Format or Minify CSS
Paste your CSS code in the input area. Click Format CSS to beautify it with consistent indentation and line breaks. Click Minify CSS to remove all unnecessary whitespace and produce compact output.
▶What CSS features are supported?
The formatter handles standard CSS including selectors, media queries, keyframes, CSS variables, flexbox, grid, and modern properties.
▶Does minification affect CSS performance?
Minified CSS files are smaller, reducing download time and bandwidth usage. The rendering behavior is identical to the original.
