What this checker can and cannot prove

PixelProof can verify measurable file properties before upload: dimensions, ratio, size, format, and basic white-edge signals. It cannot guarantee platform approval because policy checks, account eligibility, moderation, product accuracy, and ad review are controlled by the destination platform.
