AI metadata in images: what can and cannot be removed
An image can carry information about how it was created or edited. Some of that information lives in file metadata and can be removed by creating a new copy. Other signals may be embedded in the content itself and are a different matter.
What C2PA and Content Credentials are
C2PA is an open standard for associating provenance information with digital content. It can include data about the tool that created or edited an image, its change history and cryptographic signatures that help verify that provenance. Content Credentials is the name commonly used to present this information to users.
Can a ChatGPT image carry provenance data?
Yes. OpenAI states that supported images generated with ChatGPT, Codex and its API can include C2PA metadata and SynthID watermarks. That is why “removing metadata” and “making an image impossible to recognize as AI-generated” are not the same operation.
OpenAI also provides a public verification tool that looks for supported provenance signals such as trusted C2PA manifests and SynthID. If it detects no signal, that alone does not prove the file was not generated or exported with OpenAI tools: the signal may be absent, unsupported or degraded by editing, conversion or compression.
What Rusadix removes
The cleaning tool rebuilds a copy from pixels and does not copy known metadata blocks from the original into the new file. It then analyzes the output with ExifReader and an independent structural checker. In JPEG, PNG and WebP it also looks for known provenance structures such as C2PA/JUMBF when present in the file.
Removing file metadata is not a guarantee of origin anonymity. A signal embedded in pixels, an invisible watermark or external content analysis may still provide provenance information.
So why remove this information?
Mainly for privacy and file control: removing GPS location, camera data, XMP fields, software information, embedded thumbnails and other metadata you do not need to share. It can also remove provenance information stored as metadata when the new copy is rebuilt and verification confirms those blocks are no longer present.
