It can do both. A CDN can reduce the load on your hosting server, but if you choose a paid CDN and your traffic grows fast, the CDN bill can become another cost to watch.
Can using a CDN reduce my web hosting costs or increase them?
I’ve heard a CDN can reduce server load, but some CDN services also charge for bandwidth. Can a CDN actually save money, or can it make website costs higher?
Replies explain that a CDN can lower server load and bandwidth usage on the origin host, but paid CDN bandwidth, image optimization, security add-ons, or high traffic can increase costs if not monitored.
Answers & Discussion
For client sites, I have seen CDNs reduce hosting stress because static files are served from the edge. That can delay the need to upgrade hosting, especially for image-heavy sites.
Always check bandwidth pricing. Some providers are very affordable, but if you enable extra paid features like image optimization or advanced security, the total cost can change.
For my WooCommerce store, the CDN was worth it because pages felt faster and the server did not get hit as hard during sales. It did not really save money, but it helped performance.
