Can this prove an image is AI-generated?

No. It detects metadata indicators that are commonly present in AI images, such as C2PA credentials or generator tags. Metadata can be stripped or faked, so treat findings as evidence, not definitive proof.

C2PA (Coalition for Content Provenance and Authenticity) is an open standard for cryptographically-signed content credentials. Many AI tools and cameras embed C2PA manifests describing how an image was made. The checker flags when these are present.

Why does stripped metadata matter?

Sharing platforms and editors often strip metadata, so absence alone proves nothing. But an image with no metadata at all, when one would expect camera EXIF, can be a mild signal worth noting alongside other evidence.

Is my image uploaded anywhere?

No. The file is read with the browser's FileReader and scanned locally in JavaScript. It never leaves your device, so you can safely inspect private images.

Which formats are supported?

It works best on JPEG and PNG, scanning for EXIF/IPTC/XMP text segments and C2PA markers. Other formats may show fewer results because their metadata is structured differently.

AI-Generated Image Metadata Checker

AI-generated image metadata checker

AI image tools increasingly embed provenance information — and so do modern cameras. This tool reads an image in your browser and scans its metadata for signals that it was AI-generated: C2PA content credentials, generator names like DALL-E, Midjourney, or Stable Diffusion, Adobe Content Authenticity tags, and the software field that records the producing application. It also notes when an image carries essentially no metadata, which can be a weak signal in context.

How it works

You choose a JPEG or PNG file. The tool reads the raw bytes locally and searches the EXIF, IPTC, and XMP text regions for known markers: the C2PA / JUMBF manifest signature, generator strings, AI-related XMP fields, and the Software/Creator tags. Each match is listed with what it implies. The image is never uploaded — all parsing happens in JavaScript on your device. The result is a summary of indicators found plus a cautious verdict, since metadata can be removed or forged.

Tips and notes

Evidence, not proof. Metadata is easy to strip and possible to fake; weigh it alongside visual cues.
Absence is weak. Platforms routinely strip metadata, so “no metadata” alone means little.
C2PA is the strongest signal. A valid content-credentials manifest is hard to fake and usually names the producing tool.
Cross-check. Combine with reverse image search and a dedicated detector for anything high-stakes.
