Screenshots discard origin information and can be fabricated in seconds. Unlike original media files, they provide no reliable way to establish when or how an image was captured.
In disputes, audits, and claims, this distinction matters. As explained in When Photos Become Evidence, evidentiary material must stand on its own without relying on trust in the person submitting it.
Without cryptographic proof or capture integrity, screenshots fail basic evidentiary standards. Even file metadata offers little help, since it can be altered, regenerated, or stripped entirely — a problem explored in Photo Metadata vs. Cryptographic Proof.
