What ProvSeal verifies and what it does not prove

✓

What it can help verify

  • Whether a file contains C2PA Content Credentials.
  • Whether the file still matches its C2PA manifest.
  • Who signed the manifest, when certificate data is available.
  • Whether the signing certificate chains to a recognized trust source.
  • Whether a web page contains visible media with C2PA evidence.
×

What it does not prove

  • It does not prove that the visual content is true.
  • It does not detect all AI-generated content.
  • It does not guarantee that unsigned content is false.
  • It does not make test certificates publicly trusted.

Frequently asked questions

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.
