User guide

Minification removes comments and unnecessary whitespace to shrink the file and speed up your site's loading. The code stays functionally identical.

  • Serve the minified version in production.
  • Keep your readable source for development.

FAQ

Does minification change rendering?

No: it only strips useless characters (spaces, comments). Behavior is strictly preserved.

How much can I save?

Depending on the original formatting, savings often range from 15% to over 50% on richly commented files.
