Portfolium helps students and alumni showcase skills through rich, visual portfolios. The platform serves an international network of 180+ universities and community colleges, supporting 2.5M+ users who upload projects with multiple images. To keep browsing fast across devices, Portfolium needed a reliable way to resize and deliver images in many formats.
"Cloudimage not only saved us hours and hours of custom development to write our own solution to handle dynamic images, but also hours of integration because it was done in just one day."
Portfolium’s users can upload unlimited projects, often with multiple images per project. To deliver a smooth browsing experience, almost every image must be resized into at least six form factors so it looks right on laptops, tablets, and mobile devices. At the same time, the user base already exceeds 2.5 million and is expected to grow rapidly, pushing the limits of image processing and delivery. The team needed to scale infrastructure and workflows without adding operational burden.
Resize almost every user image into at least six form factors Ensure a fast, consistent experience across laptop, tablet, and mobile Scale infrastructure to support rapid growth from 2.5M toward 10M users Reduce engineering effort needed for ongoing image processingPortfolium selected Cloudimage to handle on‑the‑fly image resizing and delivery. The team could test and understand the service immediately, using sample URLs without heavy setup or SDKs. Implementation was completed in one day, eliminating weeks of custom development to build and maintain a home‑grown solution. With CDN‑backed delivery and a simple interface, Cloudimage provided a scalable path to serve multiple form factors and absorb traffic surges without complex integrations.
Adopt Cloudimage to dynamically resize and deliver images on the fly Cut custom development with a URL-based approach-no SDK required Leverage CDN-backed delivery to meet usage spikes and future growth Keep operations simple with an interface that’s easy to test and useWith Cloudimage in place, Portfolium avoided extensive engineering work for dynamic images and reduced integration time to a single day. The platform now resizes and delivers images across the required form factors, keeping browsing fast on any device. Cloudimage’s cost‑effective, simple, and scalable approach supports the existing 2.5M+ users while preparing for future growth, freeing Portfolium’s team to focus on product improvements instead of image infrastructure.
Implementation completed in 1 day, minimizing integration time Ongoing savings on engineering time for image handling Reliable, scalable delivery supporting millions of users Simple operations with a seamless end‑user experience
