About this check
What is actually readable in an image
Three things, and we read all three: an embedded C2PA manifest, an IPTC digital source type declaring synthetic origin, and the EXIF or XMP fields naming the software that wrote the file. Together these cover most images that carry provenance at all.
Why uploads so often come back empty
Social platforms and messaging apps strip metadata on upload, and re-encoding usually discards C2PA manifests. An image that carried perfect credentials at creation can arrive with nothing. Absence of a signal is therefore very weak evidence.
Formats
JPEG, PNG, WebP, AVIF and HEIC are parsed directly. The container is identified from the file's bytes rather than its extension, so a renamed file is still read correctly.
