Remove DALL·E & OpenAI C2PA Content Credentials

OpenAI attaches C2PA Content Credentials to images produced by DALL·E and ChatGPT. Inspect the signed manifest, then remove it so the file carries no provenance record.

How It Works

  1. 1

    Drop a DALL·E image; the scanner walks the JUMBF box tree inside the C2PA manifest store.

  2. 2

    The C2PA tab lists the issuing vendor, claim generator and AI assertions.

  3. 3

    C2PA and AI markers are pre-selected so the provenance manifest is removed.

  4. 4

    Clean and download an image with no Content Credentials attached.

Frequently Asked Questions

What does OpenAI attach to DALL·E images?

A C2PA Content Credentials manifest that records the tool used, the digital source type and a signed claim that the image was AI-generated.

Where is the manifest stored?

In a JUMBF box tree, carried in JPEG APP11 segments or a PNG caBX chunk depending on the file format.

Is the manifest cryptographically signed?

Yes. C2PA manifests are signed, but this tool removes the whole manifest rather than altering it, so no signature is left dangling.
