W3C TPAC 2025

TPAC, our major event of the year, gathers our community for thought-provoking discussions and coordinated work to advance the invaluable work of our groups. During the exciting week, W3C Working and Interest Groups gather and network to resolve challenging technical and social issues that the web faces.

TPAC brings together W3C technical groups, the Board of Directors, the Advisory Board, the Technical Architecture Group and the Advisory Committee.

Read more about TPAC.

The meeting is hybrid with the main in-person hub at the Kobe International Conference Center in Kobe, Japan.

W3C meetings operate under the W3C Code of Conduct and the W3C Antitrust and Competition Policy.

Press at TPAC: TPAC is a working meeting of W3C Members and groups. While most meeting records will be made publicly available online after the meeting, many participants prefer that their work-in-progress not be reported verbatim. Further, some organizations prohibit their employees from speaking to the press about in-progress work. As we don't want to inhibit participation, this event is therefore not open to the press.
