What is KaleidoDoc?

A company providing a suite of SDKs for working with PDF and office documents — generation, conversion, archiving, signing, extraction, printing, and more. Built on a re-architected PDF core: lightweight, scalable, and consistent across all platforms (iOS, Android, macOS, Windows, Linux) and available in your preferred programming language (.NET, C++, Java).

PDF Excellence

High-fidelity output tested on millions of files, with a low error rate and high-quality output. Built by a team with decades of document-processing experience, our SDKs deliver consistent, production-ready behavior you can trust across every environment and format.

Built for developers

Clear, well-structured documentation gets you started fast, and a predictable SDK behaves exactly the way you expect. Migration effort stays low even for complex workflows, with an easy trial and direct access to the engineers who built the product whenever you need it.

Modern architecture

A re-architected PDF core, free from the constraints of legacy engines. Lightweight, scalable, and easy to deploy, with low and efficient usage of resources. Definitely not a patchwork of outdated technology but a simple and clean alternative built for modern cross-platform applications.

A partner you can trust

Fair, value-based pricing, compatible licensing, and long-term partnerships designed to grow alongside your product. No hidden costs, no surprises, no getting stuck without answers — just transparent contracts and fast, direct support from the team behind the SDK.
