Kelkoo Group replaced its in-house image service with Scaleflex and now serves 30% faster, lighter WebP images across 39 markets. The marketing platform had been resizing over 300 million images from 20,000 merchants and carrying the infrastructure and support costs. Automated processing and multi-CDN delivery removed that overhead, and custom dashboards let the team track URL patterns and request parameters to tune performance.
The Company
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.
The Challenge
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.
The Solution
“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”
Stephane Bouhet
Senior Engineering Manager
Kelkoo Group adopted Scaleflex’s web performance and multi‑CDN solution to replace their in‑house service. 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.
The Results
By outsourcing image processing to Scaleflex, Kelkoo Group reduced infrastructure overhead and support needs, unlocking cost efficiencies. Automated optimization delivered 30% faster and lighter WebP images, improving user experience and Core Web Vitals. With tailored dashboards, the team monitored key KPIs-such as URL patterns and request parameters-to guide ongoing tuning and data‑driven decisions. Together, these changes enabled reliable delivery at scale across their multi‑market footprint.
