callas pdfCamp '26 spring

Are you working with callas technology and struggling with PDF files that fail in production—or wondering how to optimize your automation workflow? Then pdfCamp is for you. On March 26–27, 2026 in Berlin, you work directly with the people building the software. Bring your own PDFs and questions and tackle them hackathon-style together with the callas team and other users. There is no fixed agenda—attendees shape the sessions with their own production problems and ideas. To keep the discussions interactive and personal, seats are limited and usually fill quickly.
