C2PA Content Credentials Checker
C2PA (Content Credentials) is a signed manifest embedded in a file that records its creation and edit history, and is increasingly used to mark AI-generated or AI-edited media. This checker detects whether a file carries a C2PA manifest, entirely in your browser. Analyzed locally in your browser - nothing is uploaded.
What C2PA metadata reveals
Camera makers, Adobe, OpenAI and others attach C2PA credentials to declare provenance. Detecting the manifest tells you the file claims a documented origin. This tool reports presence; it does not perform full cryptographic signature verification, so it labels results "detected, not verified".
- Presence of a C2PA / JUMBF manifest
- Whether the file declares AI generation or editing
- Where the manifest lives (image, PDF, container)
- A clear "detected, not verified" distinction
Frequently Asked Questions
About reading EXIF, GPS, AI traces and other embedded metadata.
Content Credentials is the consumer name for C2PA, an open standard that attaches a signed record of how a file was created and edited. It is used to flag AI-generated content and prove authorship.
No. This tool detects that a C2PA manifest is present and interprets what it declares. Full signature verification against a trust list is a heavier process; the result is labelled "detected, not verified".
