C2PA View, a browser-based provenance inspector

Field notes

The tool processes files locally with the official C2PA reference implementation compiled to WebAssembly, rather than sending them to a service backend. It supports common image, video, audio, and document formats as well as detached .c2pa manifests. A built-in C2PA test-suite fixture demonstrates an amber result when the certificate is not on the published trust lists, while the accompanying explanations distinguish absent metadata from evidence of tampering.
