PDF Champion 2025

October 2025 by PDF Association staff

This year’s PDF Champion is the man who, as much or more than anyone else, is responsible for launching the institutions that undergird the modern PDF technology industry: Thomas Zellmann.

Thomas has been a steady, energizing presence from the earliest days of the PDF/A Competence Center, which he helped to found in 2006. That organization is now today’s PDF Association thanks a large part to his committment.

In the Competence Centre era Thomas was one of the most visible ambassadors of that mission, speaking and teaching across Europe to help make long-term digital preservation a practical reality for institutions and enterprises. Thomas championed “anything to PDF/A” workflows and promoted archival quality as a first-class requirement, not an afterthought. Our community is stronger because of his work.

On this basis, and as approved by the Board of Directors of the PDF Association, we send our congratulations – and a cube of engraved aluminum – to Thomas Zellmann, PDF Champion for 2025!
