I recently added the ability to read and verify C2PA Content Credentials in the Exify extension.

Images with embedded Content Credentials are few and far between and it remains to be seen whether wide adoption of the C2PA standard will actually happen, but in the rare cases where the data is available, it can be easily viewed using Exify.

You can try Exify here (no need to install it first): https://www.exify.io/
