What Gemini & Imagen adds to your images
Images created or edited with Google Gemini app and Imagen carry SynthID, Google DeepMind invisible watermark. Depending on the product, Google can also add metadata and a visible mark.
Markers and metadata
| Marker | What it is |
|---|---|
| SynthID | An invisible watermark in the pixels. Not visible in metadata; checked with Google SynthID Detector or Gemini. |
| Visible mark | Some Gemini app images include a small visible Gemini mark. |
| Metadata | Some Google products also add IPTC or C2PA metadata. Run your file through the checker to see what yours has. |
SynthID is designed to survive cropping, compression and screenshots, unlike metadata.
