ChatGPT Image Checker
Check images generated or edited via ChatGPT for C2PA Content Credentials manifests, cryptographic digital signatures, and provenance metadata in browser RAM.
ChatGPT Export Characteristics:
OpenAI implements C2PA Content Credentials across image generations. Direct downloads can contain cryptographic manifests. Screenshots or re-encoded files typically lose this metadata.

Drag & drop a JPG, PNG, or WebP file (or up to 30 images for batch checking), or click to browse.
How OpenAI Implements C2PA in ChatGPT
OpenAI incorporates C2PA standards into ChatGPT (DALL-E 3) generations to provide provenance transparency. When you generate an image in ChatGPT and download it directly:
OpenAI appends a standardized JUMBF box (APP11 segment in JPEGs or caDX chunk in PNGs) storing digital certificates.
The manifest is digitally signed using an X.509 certificate issued to OpenAI, linking pixel hashes to generation claims.
Checking vs. Cleaning ChatGPT Metadata
Depending on your workflow, you may want to verify provenance or sanitize private assets:
Verify whether an image carries genuine OpenAI Content Credentials.
Strip C2PA manifests losslessly before publishing to protect prompt techniques.
Automatic second-pass re-scan confirms targeted signals are no longer detected.

Frequently Asked Questions
What metadata can ChatGPT-generated images contain?
OpenAI attaches C2PA (Coalition for Content Provenance and Authenticity) Content Credentials to images generated on ChatGPT. These manifests include cryptographic provenance assertions declaring that the image was synthesized by OpenAI models, along with digital signing certificates and timestamps.
Does every ChatGPT image export contain C2PA metadata?
Direct original downloads from the ChatGPT web application or mobile app typically retain C2PA metadata. However, taking a screenshot, saving through a web browser that re-encodes, or sharing via messaging apps like WhatsApp or Discord strips the metadata container.
Does the absence of metadata prove an image wasn't made with ChatGPT?
No. Metadata is fragile. If an image is converted, screenshotted, or stripped of its header data, our checker will report that no supported AI metadata was detected. This technical limitation is inherent to container metadata inspection.
Can I strip ChatGPT C2PA Content Credentials from my image?
Yes. Our integrated lossless cleaner removes C2PA JUMBF containers without recompressing image pixels. Visual fidelity, resolution, and color profiles remain 100% unaltered.
Are my ChatGPT images uploaded to any server for scanning?
No. All parsing and cryptographic manifest extraction occur directly in your browser's local memory. Zero image bytes are uploaded to remote servers or cloud AI APIs.
