01 / Context
The problem
Everyday image, PDF, developer and SEO tasks are scattered across ad-heavy websites that upload private files to a server. The product needed to offer a wide range of utilities while keeping processing entirely on the user's device.
02 / Delivery
What we delivered
A unified Next.js application with a shared tool registry, consistent interface patterns across every utility, and client-side processing so documents and images stay on the device. A common design and engineering system allows new tools to ship without redesigning the experience each time.
