Check the C2PA Content Credentials in an image
C2PA Content Credentials are a signed provenance manifest that cameras, Adobe and many AI tools embed to record how an image was made and edited — including whether generative AI was involved. MetaMarshal runs a byte-level scan to tell you whether that manifest is present and shows you what it claims, so you can verify provenance rather than take an image at face value.

🔒 Processed on your device — nothing is uploaded unless you tap the optional AI estimate.
Nothing leaves your device to clean a photo — the only exception is the optional AI location estimate, which sends a downscaled copy off-device, and only after you tap to confirm.
How it works
1
Drop an image above; the byte-level scan reads it locally and looks for an embedded C2PA manifest.
2
See whether Content Credentials are present, and review the claims they carry — capture, edit history and any AI-generation assertions.
3
Cross-check the provenance signals against the rest of the metadata to judge how trustworthy the file's history looks.
4
Use the read-only view to verify and understand the credentials — MetaMarshal surfaces provenance, it doesn't help you forge or hide it.
They're a tamper-evident record of an image's origin and edits, backed by a cryptographic signature. Journalists, platforms and buyers use them to verify where a picture came from and whether AI had a hand in it.
