Kelkoo Group is a leading marketing platform that uses machine learning-powered technologies to help retailers increase sales. Operating with a network of 1,000 partners across 39 markets, the team needed to modernize how they processed and delivered vast volumes of product images at speed and scale.
"Outsourcing the image processing service allowed us to reduce our infrastructure, limit support and benefit from additional features such as support for images in WebP"
Kelkoo Group previously relied on an in-house media optimization service. As their marketplace scaled, they ran into operational strain: maintaining a large infrastructure, resizing over 300 million images from 20,000 merchants, and ensuring fast delivery worldwide over a CDN. The internal service demanded ongoing support and costs, while the volume and variety of inputs made consistent performance difficult to guarantee.

Automated image processing produced lighter WebP images on-the-fly, while delivery was handled via a multi‑CDN set‑up. Custom dashboards gave the team visibility into URL patterns and parameters, helping them track performance and optimize where it mattered most.
