Yes, bulky and unoptimized JavaScript and CSS files can significantly slow down your Webflow store, affecting both user experience and search performance. When your pages take too long to load or respond, visitors quickly lose interest, causing higher bounce rates and fewer conversions. Heavy code makes your site feel sluggish, especially for mobile users who already deal with slower connections and limited bandwidth.

It removes unnecessary characters, extra spaces, comments, and formatting - all while preserving your site’s original design and functionality. This means your store becomes lighter, faster, and more responsive without requiring any technical expertise.
