Gemini Image Detector — Check if an Image is Made by Google Gemini

How to use

Drop the image
Drag a PNG, JPEG, or WebP file into the drop zone. The file is read locally in your browser.
Read the detection report
The inspector checks for SynthID watermarks (Google's pixel-level watermark for Gemini/Imagen images) and C2PA Content Credentials. Each detection is shown with evidence.
Understand the verdict
The verdict tells you whether the image carries Gemini/Imagen fingerprints. A positive match means the image was likely generated by a Google AI model.

Frequently asked

Can I detect if an image is from Google Gemini?

Yes. Drop the image into the AI Image Inspector on this page. It checks for SynthID, Google's watermark technology, and C2PA Content Credentials that Gemini embeds.

What is SynthID?

SynthID is Google DeepMind's digital watermark that embeds an imperceptible signal into AI-generated image pixels. The inspector detects this signal alongside C2PA metadata.

Limitations

SynthID detection has limitsSynthID is designed to survive compression and small edits but breaks under heavy cropping, re-encoding, or screenshotting. The detector reports confidence scores per signal.
Screenshots defeat detectionTaking a screenshot strips C2PA manifests during re-encoding and weakens pixel-level SynthID signals. The screenshot may read as inconclusive or as 'No AI generation traces found.'
PNG, JPEG, and WebP onlyThe C2PA chunk reader and SynthID detector work on PNG, JPEG, and WebP. AVIF, HEIC, and TIFF are not decoded.

Platform notes

macOS: Preview.app and Quick Look do not surface C2PA Content Credentials. SynthID is invisible to all OS tools — the inspector is the only way to detect it without uploading.
Windows: Windows Photos and File Explorer show EXIF but not C2PA or SynthID. For full Gemini provenance, drop the file into the inspector.
Linux: `exiftool -api RequestAll=3 image.png` shows C2PA claim chains and XMP, but not SynthID. The inspector is the right pick for combined C2PA + SynthID detection.
Web: Runs entirely client-side. The image is read as a Uint8Array; C2PA, SynthID, EXIF, and XMP detectors all run as pure JavaScript. No upload, no server roundtrip, no telemetry.
