About the CSS Minifier

The CSS Minifier uses a scanner that protects quoted strings while removing comments and redundant spacing around punctuation. It preserves the final semicolon only when needed for correctness.

How to use the CSS Minifier

  1. Paste valid CSS.
  2. Run the local minifier.
  3. Test visual output and download the compact stylesheet.

Practical tips

  • Keep the readable source in version control.
  • Check uncommon hacks or custom templating constructs after minification.
