AI Image Detector

Check if an image was AI-generated — C2PA credentials, generator signatures, metadata, and frequency analysis. Everything runs locally in your browser; images are never uploaded.

Drop an image here

JPEG · PNG · WebP — processed locally, never uploaded

How to use:

  1. Drop or select a JPEG, PNG, or WebP image. It is analyzed entirely on your device.
  2. Click "Analyze Image". The tool checks C2PA credentials, AI generator signatures, metadata, and pixel frequency.
  3. Read the verdict and evidence cards. C2PA verification is the strongest signal; frequency analysis is heuristic.

Frequently Asked Questions

How does the AI image detector work?+
It runs four checks in your browser: C2PA / Content Credentials verification (the strongest signal), AI generator signatures in metadata (Midjourney, Stable Diffusion, DALL-E, SynthID, etc.), structured metadata, and byte-level frequency anomalies that synthetic images often leave behind.
Are my images uploaded to a server?+
No. Every check runs entirely in your browser. The image never leaves your device — there is no upload and no server-side processing.
Can the detector prove an image is AI-generated?+
Not with certainty. Detection is probabilistic. C2PA credentials that state an AI source are strong evidence, but metadata can be stripped and frequency analysis is a heuristic. Treat the verdict as one signal, not proof.
What image formats are supported?+
JPEG, PNG, and WebP. These are the formats that carry the metadata and byte-level signatures the detector looks for.
Why does my AI-generated image show no signals?+
Many generators strip metadata, and some AI images are statistically very close to natural ones. If no signal is found, the tool reports "No AI-generation signal found" — that is an absence of evidence, not evidence of absence.
