ChatGPT image lab: what can still be in the file you saved?
When I save an image from ChatGPT, can it still carry ordinary metadata or C2PA, and does a miss mean it is a photograph?
A ChatGPT save may still hold ordinary metadata or C2PA, or it may hold neither. Neither result does not prove a photograph. A screenshot drops the original container, so read the file you saved. Clean the copy in this browser before sending. The file stays on this device and is not uploaded to this site.
Some saves keep a container. A screenshot throws that container away, including C2PA if it was there. One save does not define every ChatGPT image.
Short answer
Direct answer: the file you saved might hold ordinary metadata, C2PA, or neither. Neither is not a camera certificate.
- File facts: Read the file you actually saved. Do not substitute a different download.
- What that does not prove: The local sample on related lab pages is not presented here as an official ChatGPT export.
- What you can do first: Open the saved file in this browser before you share it. It is not uploaded to this site.

How to test your own file
- Download the image from ChatGPT, do not screenshot.
- Inspect C2PA, EXIF, XMP, PNG text locally.
- Optionally run official verification where a vendor provides it.
- Record model/product UI version.
Methodology
Every published result has to follow the same protocol: a known source file, a recorded hash, a specific upload path, and a downloaded copy. Folklore does not count.
Privacy implications
If you need to inspect origin claims, use the original download, not a screenshot. Do not advertise a detector as 100% accurate.
