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.
Amazon Seller Central guidance calls out pure white backgrounds, no extra graphics, accepted formats, and at least 1000 pixels on the longest side for zoom.
