Hello,
With this charter review notice, the W3C Team initiates refinement for a
draft Portable Network Graphics (PNG) Working Group charter:
https://w3c.github.io/charter-drafts/2025/png-wg.html
PNG Third Edition, which is a W3C Recommendation, was a major update. It
is widely implemented. PNG Fourth Edition is planned to be a smaller
update, focused on improving HDR & Standard Dynamic Range (SDR)
interoperability. In parallel, the group will do longer-term work on
researching compression updates (including parallel encoding and
decoding) for PNG Fifth Edition.
We encourage early discussion of this draft charter in this public forum:
https://github.com/w3c/charter-drafts/issues
W3C Members may discuss on the member-confidential mailing list
<w3c-ac-forum@w3.org>.
Section 4.2 of the Process Document [1] describes activities during
charter refinement and the role of the Chartering Facilitator to seek
consensus among those who provide feedback about the charter.
The W3C Team estimates that this charter refinement will last until
approximately 15 October 2025.
If you should have any questions or need further information, please
feel free to contact the Chartering Facilitator, Chris Lilley
<chris@w3.org>.
The current charter [2] is hereby extended until 30 January 2026 to
cover the time needed for the rechartering process.
More information about the group can be found on its home page [3],
including information about group Chair, Staff Contact, and instructions
for joining the group.
This announcement follows sections 4.1 and 4.6 of the Process Document:
