AI image metadata checker
Check an image for labels that say how it was made: Content Credentials, the IPTC digital source type, and prompts left behind by image generators.
JPEG · PNG · WebP · HEIC · AVIF · TIFF
Or drop a file here, or paste an image.
Your file is read by this page, inside your browser. It is never uploaded.
What the checker looks for
- Content Credentials (C2PA): a signed record of where a file came from and how it was edited[1]. The checker reports whether one is present, the app that wrote it, and whether it names an AI source type.
- IPTC digital source type: a standard label. For example,
trainedAlgorithmicMediameans created by a generative AI model, andcompositeWithTrainedAlgorithmicMediameans edited with one[2]. - Generator text: prompts and settings that some image generators save into PNG files, such as Stable Diffusion web UI parameters or ComfyUI workflows.
What these labels can't tell you
No label does not mean "real". The C2PA explainer says provenance metadata can be removed, and that no assumption should be made about an image's trustworthiness only from whether it has Content Credentials[1]. Screenshots, re-saves and uploads often strip labels.
- A label is not a verdict. Validating Content Credentials checks the signature and that the file hasn't changed since signing. It does not decide whether the content is true[1].
- This checker detects; it doesn't validate. It doesn't check signatures. To validate Content Credentials, use the Content Authenticity Initiative's Verify tool[3].
- Plain text fields can say anything. Anyone can write a prompt into a PNG text chunk, or an IPTC label into XMP.
- It is not an AI detector. It does not analyze pixels.
Removing these labels
The cleaner removes them along with other metadata, for example to take your prompt out of an image before you share it. Removing provenance doesn't change how an image was made, and many platforms and publications expect AI-generated images to be disclosed.
