Verify an image locally
- Install ProvSeal and open the extension popup.
- Use the local file card and choose a supported JPG or PNG image.
- Read the status: Trusted, Signed but untrusted, Invalid or No credentials.
- Open the report to inspect manifest data, signature validation and certificate-chain status.
What a result can tell you
It can show whether C2PA evidence exists and whether signed data still validates against the image.
What it cannot tell you
It does not decide whether the image is true, fake or AI-generated. It reviews provenance and integrity signals.
