Shopify now serves minified CSS files automatically


As of May 2021, Shopify will automatically minify theme CSS when it is requested by the storefront. Minified CSS files are cached until the next time the underlying CSS file is updated.

Minification improves storefront performance, leading to a better buying experience for customers.

Learn more about performance and its benefits in the Shopify Help Center.
