The PDF Technical Working Group (TWG) is dedicated to supporting developers with publications and other resources to assist in creating software to comply with ISO 32000, the International Standard for the Portable Document Format (PDF).
The members of the TWG come from a variety of backgrounds, but are primarily developers working for vendors creating products that create or consume PDF files. Some members are also actively involved in the ISO PDF committees which set the international standards that define PDF technology. Together, we have a wide and deep experience of PDF, both theoretical and practical. We are therefore ideally placed to discuss any ambiguities in the standard, to jointly develop best practices, and to share advice, e.g. to ensure that PDF files are appropriately prepared for their target use cases and audiences.
The PDF Technical Working Group (TWG) is a collaborative organization of PDF software developers who use the TWG’s resources to share their knowledge and experience of PDF technology in a vendor-neutral space.
Members of the PDF Association are entitled to participate in online and in-person PDF TWG meetings, subscribe to the PDF TWG listserv, access the PDF Association’s Jira, and much more!
