Pure white background, how much of the frame the product fills, size and shape, measured against Amazon, Walmart, eBay, Etsy and more.

Lens reads the picture's pixels on your device and measures what the marketplaces ask for: the share of the edge that is pure white (255, 255, 255) and nearly white, how much of the frame the product fills (Amazon and Walmart want 85%), the size on the longest side, whether it's square, and any transparency that some sites show as black. Every check shows the number it measured and what's needed, marked as a rule or guidance.
