What are Content Credentials?

C2PA Content Credentials are signed manifests embedded in a file that record which tool created or edited it. Adobe Firefly, OpenAI image tools, several cameras and editing apps write them.

This checker reads the manifest, the signer and the validation state, and flags AI-generation declarations when present. A missing manifest is the normal case for most files online and does not indicate that content is human-made.

Frequently asked questions

Is my file uploaded during C2PA verification?

No. C2PA verification runs client-side in your browser.

What does "Invalid" mean?

The manifest exists but its signature or hashes do not match the file, typically because the file was modified after signing.
