C2PA Content Credentials Checker
Upload an image or audio file to inspect C2PA manifests and their validation state.
What this checker can verify
- Whether a readable C2PA manifest is present.
- Whether validation is trusted, incomplete, or invalid when local verification is available.
What it cannot verify
- The factual accuracy or ownership of the content.
- A complete history after credentials have been removed.
How to interpret the result
A trusted signature is strong evidence about provenance. An invalid manifest is not treated as absent; it is shown as a warning.
No supported signal detected does not prove a file was created by a human. Metadata and credentials can be removed by screenshots, exports, editing, compression, or unsupported services.
