If you’re uploading thousands of products to Amazon, eBay, Walmart, or any other marketplace using flat files (CSV, Excel, XML), one thing matters more than you might think: where your product images are hosted.
Image URLs in inventory feeds must be fast, reliable, and globally accessible, or your listings risk being rejected, loading slowly, or not appearing correctly. In this article, we compare the best image CDNs using real-world uptime and speed data, so you can choose the right host for your flat file product feeds.
Inside this article
Why your image CDN matters for flat files
Marketplaces don’t just store your images, they crawl your image links. If your CDN is down or slow:
- Your images might not be processed in time
- Listings could get suppressed or flagged
- Your pages could load slowly for international buyers
A good image CDN ensures:
- 99.99%+ uptime, so your links are always reachable
- Low latency worldwide, especially for platforms crawling from the US, EU, or Asia
- Direct access to image files with public, stable URLs (not tokenized or expiring)
CDNs compared: Uptime & Speed test
We used real monitoring data from Hyperping’s CDN benchmark to evaluate the top image CDNs across two key metrics:
- Uptime: How often the CDN responded successfully
- Speed: How fast the CDN served an image URL globally (average response time in ms)
✅ CDNs included:
- Specialized in image hosting for product inventory files:
- Img.vision
- Cloud drives:
- Google Drive
- OneDrive
- Dropbox
- Traditional server hosts:
- MyTrueHost
- Turbify
- Free image hosting sites:
- PostImage
- Imgur
- FreeImage.host
- Imghippo
- YourImageShare
- Tinypic.host
- imgbb

📌 Note: Data was collected using regular pings to a hosted image on each service, from multiple regions.
