Top 5 Image Optimisation CDNs in 2026

Our 2026 ranking helps you compare CDNs that list image optimisation, with particular attention to origin storage, delivery reach and relative cost. Use it to shortlist a provider, then check that its image tools support the exact resizing and format options your site needs.

How we ranked these image CDNs

We ranked the five providers that list image optimisation, weighing that feature alongside origin storage and the relative cost signals shown in our comparison. Those factors matter when you want to serve optimised images without adding a separate storage service or taking on an unexpectedly costly delivery setup. We also considered network reach, HTTPS on your own domain, cache controls and useful security features. We rank on listed specifications and features, not lab tests. The providers do not all describe their image tools in equal detail, so the optimisation flag alone does not confirm which resizing controls, output formats or automatic transformations are available.

1. Bunny CDN by Bunny.net

Bunny takes the top spot for combining listed image optimisation with origin storage and HTTPS on your own domain. That pairing gives you a practical starting point if you want one provider to store and deliver image assets. Its network covers 81 countries through 119 PoP locations, including the Netherlands, and it supports HTTP/2, compression and cache purging. Bunny also lists comparatively low delivery rates for Europe and North America, although transfer charges vary by region.

• Strengths: Image optimisation and origin storage are both listed; HTTPS is available on your own domain; 119 PoP locations and coverage across 81 countries; purge by file, wildcard or tag/key, as well as a full purge.
• Strengths: Supports small and large files, hotlink protection, token authentication, statistics and an API.

• Limits: No WAF, DDoS protection or Origin Shield is listed; it does not list dynamic content delivery or HTTP/3; support is by email, with no listed 24/7 availability.

Choose Bunny if you want image optimisation and origin storage together, and your priority is a broad network with a comparatively economical regional delivery rate. Check how its image tools handle resizing before migrating an image library, because the feature flag does not specify available transformations.

2. Cloudflare CDN by Cloudflare

Cloudflare is the strongest fit here if you want image optimisation alongside a broad network and extra security features. It lists 309 PoP locations in 121 countries, including 37 locations in China, plus a PoP in the Netherlands. HTTP/3, edge computing, dynamic content delivery, a WAF and DDoS protection set it apart on capability. Its listed Europe and North America traffic has no charge, making it a notable option for cost-conscious delivery.

• Strengths: Image optimisation, HTTP/3, edge computing and dynamic content delivery; WAF and DDoS protection; 309 PoP locations; listed traffic in Europe, North America, Latin America and Asia-Pacific has no charge.
• Strengths: HTTPS on your own domain, hotlink protection, token authentication, WebSockets and purge by file.

• Limits: Origin storage is not listed, so you may need a separate source for image files; Origin Shield and log files are not listed; you cannot use your own SSL certificate according to the listing.

Pick Cloudflare if security, network reach and listed traffic costs matter more than bundled origin storage. Its listed image-optimisation flag does not spell out resizing controls, so confirm that the image workflow you need is included in the plan you intend to use.

3. Gcore CDN by Gcore

Gcore pairs image optimisation with origin storage, a WAF and DDoS protection. It also lists HTTP/3, an own SSL certificate, edge computing and dynamic content delivery. Its network spans 78 countries and 104 PoP locations, with a Netherlands PoP. For Europe and North America, its listed delivery rate is higher than Bunny’s, while the feature set includes useful controls such as serving stale content and purging by pattern.

• Strengths: Image optimisation and origin storage; WAF and DDoS protection; HTTP/3, edge computing and dynamic content delivery; own SSL certificate and HTTPS on your own domain.
• Strengths: Serves stale content, supports private CDN setups and offers purge by file or pattern as well as a full purge.

• Limits: Its network has fewer listed PoP locations than Bunny or Cloudflare; no PoPs in China are listed; it does not list 24/7 availability; charges apply per request.

Gcore suits you if you need origin storage and want security and delivery features in the same CDN. Consider it against Bunny if both fit your image workflow: Gcore lists more security features, while Bunny has more PoP locations and a lower listed Europe and North America transfer rate.

4. CacheFly CDN by CacheFly

CacheFly is a useful choice when image delivery needs origin storage plus Origin Shield. It also lists image optimisation, a WAF, DDoS protection and HTTPS on your own domain. The network covers 45 countries with 71 PoP locations, including two in China and one in the Netherlands. CacheFly lists 24/7 availability and phone support, which may suit teams that want more than email as a support channel.

• Strengths: Image optimisation, origin storage and Origin Shield; WAF and DDoS protection; own-domain HTTPS; 24/7 availability and phone support.
• Strengths: Lists serving stale content, private CDN, HTTP/2, WebSockets and purge by folder.

• Limits: Its network has 71 PoP locations across 45 countries; DNS, edge computing and apex/root-domain support are not listed; the minimum contract is one month.

Choose CacheFly if Origin Shield, storage and round-the-clock availability outweigh having the largest possible network. Its listed delivery rate for Europe and North America is higher than Bunny’s, and its China presence is limited to two PoP locations.

5. Fastly CDN by Fastly

Fastly rounds out the ranking with image optimisation, Origin Shield, edge computing and a broad set of security features. It lists a WAF, DDoS protection, HTTP/3 and dynamic content delivery, plus 67 PoP locations in 35 countries. It also offers log files, serve-stale behaviour and purge by tag/key. The trade-off is a higher relative cost: its listed delivery rates are higher than the other providers ranked here.

• Strengths: Image optimisation, Origin Shield and edge computing; WAF and DDoS protection; HTTP/3, WebSockets and dynamic content delivery.
• Strengths: Logs are listed, alongside purge by tag/key, serve stale and HTTPS on the CDN domain.

• Limits: Origin storage and HTTPS on your own domain are not listed; the network has 67 PoP locations across 35 countries; DNS is not listed; the minimum monthly commitment is comparatively high.

Fastly suits teams that value edge and security features and can justify the higher relative cost. For a straightforward image library, Bunny or Gcore may be better starting points if you want origin storage included.

Why EdgeNext did not make the list

EdgeNext lists image optimisation and 1,222 PoP locations, but HTTPS on your own domain is not listed. That limitation matters for a typical image CDN setup serving assets from your site’s hostname, so it misses this top five.

How to choose an image CDN

Start by checking what “image optimisation” means in the provider’s actual service. This comparison confirms which providers list the feature, but it does not specify whether you can resize images on demand, set width and height parameters, convert formats or control compression. If your site generates several image sizes for product cards and full-screen views, verify those operations and test how they fit your existing image URLs before switching.

Next, decide whether you need the CDN to store your original files. Bunny, Gcore and CacheFly list origin storage; Cloudflare and Fastly do not. If your images already live on a separate origin, that missing feature may not matter. If you want fewer moving parts, compare storage and delivery in one service, while checking how you will upload and manage the files.

Match network coverage to your visitors, not just the largest PoP count. Cloudflare lists the broadest reach here and PoPs in China; Bunny has 119 locations and coverage across 81 countries. If most requests come from one region, the listed regional delivery rate may matter more than a global location count. Finally, review HTTPS on your own domain, cache purge options and security needs. Those details affect how you deploy image URLs, refresh changed assets and protect the rest of your site in 2026.
