How CDNs Deliver Images Faster

A CDN (content delivery network) is a network of servers in many locations. When someone requests an image, the CDN serves it from a server near them, reducing distance and latency so the image loads faster.

CDNs also cache images at the edge, so repeated requests are served from cache instead of the origin server. This reduces load on your host and improves reliability during traffic spikes.

Many image and cloud hosts use CDNs behind the scenes. When you upload to a modern image host, your files are often distributed automatically, so you get faster delivery without extra configuration.
