| Field | What we found / documented |
|---|---|
| Watermark type | SynthID, embedded in the pixels, invisible to the eye |
| Readable in a standard EXIF/metadata viewer | No |
| Detectable after cropping or recompression | Designed to be, per Google DeepMind |
| C2PA Content Credentials | Google has stated support for content-credential style labeling in some products |
SynthID works differently from the metadata this site inspects: it is embedded directly in the image signal, not in a text field or credential container, so tools that read EXIF, PNG text chunks, or C2PA manifests will not show it either way. Verifying a SynthID watermark requires Google's own detection tooling, which is separate from file-metadata inspection.
That distinction matters practically: a Gemini or Imagen image can show no camera EXIF, no generation text field, and no C2PA marker in our Content Credentials inspector and still carry a SynthID watermark you cannot see with any of these tools. Treat an empty metadata result on a suspected Gemini/Imagen image as inconclusive rather than as evidence the image is not AI-generated.
Questions this page answers
Does an empty metadata result mean the image is not from Google Gemini / Imagen?
No. A missing field can mean the metadata was never written, was stripped by an export or upload step, or was not inspected by this tool. Treat it as inconclusive, not as proof either way.
Does this page verify a specific image is from Google Gemini / Imagen?
No. It describes documented or observed behavior for Google Gemini / Imagen in general. To evaluate one file, inspect it with our metadata viewer and Content Credentials marker inspector and weigh the result alongside other context.
