Trusted

Valid and recognized

Valid Content Credentials plus a recognized trust chain from the C2PA Trust List.

Signed but untrusted

Valid signature

The signature is valid, but the certificate is not from a publicly trusted authority.

Invalid

Integrity failed

C2PA data exists but integrity or signature validation failed.

No credentials

No C2PA evidence

No C2PA evidence detected. This does not mean the content is fake.

Common questions

Straight answers about local verification, trust status and what ProvSeal does not claim to do.

View all FAQ answers

Does ProvSeal upload my files?

No. Verification is designed to run locally in your browser. Your files are not uploaded to a ProvSeal backend.

Does No credentials mean fake?

No. It means no C2PA manifest was detected. Many authentic images do not yet carry Content Credentials.

Can it detect AI-generated images?

No. It can show declared tooling and actions when credentials are present, but it is not AI or fake detection.

What formats are supported?

ProvSeal supports verification workflows for JPEG, PNG, PDF, MP4, MOV and WebM. Signing supports JPEG, PNG and PDF.
