Amazon strictly requires: Pure white background (RGB 255, 255, 255); product must fill at least 85% of image frame; recommended 1:1 square ratio; minimum 1000px longest side (ideally 1600-2000px for hover zoom); no text, badges, borders, or watermarks.
Even studio photography often produces RGB(248, 248, 248) off-white backgrounds near edges. Amazon automated bots sample these pixels and suppress listings. Our tool detects sub-visible gray casts and purifies them instantly.
Never. The tool employs non-destructive geometric recalculation and lossless canvas synthesis, fully preserving every pixel of product texture and edge sharpness while cleaning the background.
Not at all. Dopic follows a strict Privacy-First client-side architecture. All audits and fixes execute 100% inside your local browser memory with zero network uploads.
It outputs a standard 2000 × 2000 px 300 DPI high-res sRGB square image, perfectly satisfying Amazon requirements across all international marketplaces.
