C2PA & Content Credentials Checker

Validate C2PA Content Credentials without installing anything and without uploading your file — parsing, signature validation and provenance history run in your browser via the official CAI engine.

Your image is inspected locally in this browser tab. Nothing is uploaded.

What you'll see in a result

  • Manifest found / not found — whether the file carries Content Credentials at all.
  • Signature stateTrusted (valid and on the C2PA trust list), Valid (cryptographically intact) or Invalid.
  • Signer — the certificate holder that vouches for the record.
  • Claim generator — the software that produced the manifest (an AI model, a camera, an editor).
  • Digital source type — including trained algorithmic media, the standard’s term for AI-generated content.
  • Actions and ingredients — recorded edit history and source files, when present, plus the full raw manifest behind “technical details”.

How C2PA differs from a watermark

Content Credentials are signed metadata that travel with the file — an evidence label, not a hidden mark. Anyone can verify them (that’s the point of an open standard), and any tampering with the file breaks the signature visibly. The trade-off: metadata can simply be stripped. Invisible watermarks like SynthID take the opposite trade — they survive edits better but only their provider can read them. Modern providers increasingly use both layers; the background is in our C2PA explainer.
