Adobe co-founded the C2PA standard (alongside Microsoft, Intel, ARM, Truepic, and the BBC in 2021) and has embedded Content Credentials in every Firefly-generated image since launch. Expect a complete, signed manifest: claim generator naming Adobe/Firefly, a trainedAlgorithmicMedia digital source type, and a cryptographic signature — Firefly is effectively the reference implementation of C2PA among consumer AI tools.
Because Adobe sits on the C2PA steering committee and built the Content Authenticity Initiative (CAI) that preceded the formal standard, Firefly's manifests tend to be more complete than many other tools': proper claim generator identification, a full assertions list, and consistent signing. This is also why platforms that read C2PA (Instagram, Facebook, TikTok) detect Firefly images especially reliably.
AiEraser's View mode decodes the real manifest structure on your file — the same JUMBF/CBOR decoding we use for any C2PA-compliant source — and Remove mode strips it via browser-side canvas re-encoding.
