Applies to main product images only. Secondary images may have different rules.
Based on official marketplace seller guidelines.
Amazon requires the main product image to have a pure white background — specifically RGB 255,255,255. Off-white, cream, or light grey backgrounds that look white on screen are flagged by Amazon's automated systems and can cause listing suppression or rejection.
How this tool measures whiteness
This checker uses a threshold of RGB ≥ 240 to flag near-white pixels. To safely meet Amazon's strict requirement, aim for a whiteness score of 85% or higher and color uniformity below 8 standard deviations.
