C2PA View

How do I check if an image is AI-generated?

Drop it in above. If the generator added Content Credentials (DALL-E, Adobe Firefly, and others do), the actions list will say so - this page flags entries whose digital source type is trained algorithmic media as AI-generated. Absence of credentials does not prove a file is not AI-made: most AI images circulating online have had their metadata stripped by social platforms.

What does a green result prove?

That the file carries Content Credentials, the cryptographic checks pass, the file has not been modified since signing, and the signer's certificate chains to the published C2PA trust lists. If the file is intact but the signer is not on those lists, an amber result says so - the identity of the signer can't be verified. A red result means the file was changed after signing.

Why does my file have no Content Credentials?

That is the normal case. Only recent cameras and apps sign their output, and most websites and messaging apps strip metadata on upload - a signed photo posted to social media usually comes back out unsigned. No credentials means no provenance information either way: it is not evidence of tampering.

Is my file uploaded anywhere?

No. Validation is done by the official C2PA reference implementation compiled to WebAssembly, running in your browser. This site has no backend, no accounts, no analytics and no cookies; the file's bytes never leave your machine. Load the page, go offline, and it still works.

Which file types are supported?

JPEG, PNG, WebP, AVIF, GIF, TIFF, SVG, MP4, MOV, MP3, WAV and PDF, plus detached .c2pa sidecar manifest files - the formats the C2PA specification defines embeddings for.
