Can any third-party website detect Google SynthID?

Be cautious of tools claiming instant client-side SynthID detection. SynthID verification relies on Google's proprietary detection models and keys.

Why check an image here first?

Many Google Imagen and Gemini exports also include IPTC/XMP tags ('Made with Google AI' or 'trainedAlgorithmicMedia') or C2PA headers, which this tool reveals instantly in your browser.

Can Canvas re-encoding remove Google SynthID?

No. SynthID is embedded in pixel and frequency patterns designed to survive cropping, resizing, and re-encoding.

Google SynthID: Detection Limits & C2PA Checker

Verify whether an image carries C2PA Content Credentials or EXIF/XMP AI tags locally, and understand how Google SynthID differs.

Transparency Note on Google SynthID: No client-side browser tool can reliably detect or remove pixel-level Google SynthID watermarks. This inspector checks C2PA Content Credentials, EXIF/XMP/IPTC AI generator tags, and PNG prompt metadata locally. For SynthID pixel verification, use Google's official SynthID Detector portal.

SynthID vs. C2PA vs. EXIF Metadata

Google SynthID (Pixel / Token Level)

Embedded directly into pixel patterns or LLM token probabilities using proprietary keys. Only Google's official SynthID Detector can verify it.

C2PA Content Credentials (Header Level)

Open standard stored in file headers (JUMBF/XMP). Any local inspector can read whether a C2PA claim is attached.

EXIF, IPTC & PNG Chunks

Plain-text and structured tags written by Imagen, Firefly, Stable Diffusion, and ComfyUI—fully inspectable and removable in your browser.
