Photon is WordPress.com's built-in Content Delivery Network (CDN) designed to significantly improve the performance of WordPress.com websites. It achieves this by offloading the delivery of images and static assets (like JavaScript and CSS) to WordPress.com's global network of servers.

The site accelerator is particularly beneficial for WordPress.com users on Business and Commerce plans who want to enhance their site's speed and user experience. It automatically optimizes images by resizing them and serving them in modern formats like WebP to compatible browsers. For static files, it caches and delivers core WordPress, Jetpack, and WooCommerce assets. By distributing content across multiple subdomains, it also leverages parallel downloads to further speed up page load times, making websites more responsive and efficient.
