Content Credentials checker
Content Credentials are the C2PA standard's answer to provenance: a structured manifest embedded in the file recording what made it and what was done to it since. Adobe, OpenAI, Google, Leica and Sony all write them, and they are the most trustworthy signal available about an image's origin.
This tool extracts the manifest from whichever container the image uses and reports what it says, including whether it carries the IPTC assertion for AI-generated media.

Frequently asked questions
What is C2PA?
An open standard from the Coalition for Content Provenance and Authenticity, backed by Adobe, Microsoft, the BBC and others, defining how to attach a tamper-evident record of origin to a media file.
Is the signature verified?
Not here. Full verification requires the C2PA reference implementation, which is impractical to run in this environment. We read the manifest and report what it claims, which is useful but is not the same as proving it authentic.
Why do most images have no Content Credentials?
Adoption is still early, and almost every social platform strips metadata on upload. Absence tells you very little; presence tells you a lot.
