Does Amazon require a white background for product images?
Yes for the main image: Amazon's image guidelines require a pure white background (RGB 255, 255, 255) with the product filling most of the frame and no props, text or watermarks. Additional images can show lifestyle scenes. Flipkart and most marketplaces have the same main-image rule.
A photographed white sweep is rarely pure white — it comes out light grey with shadows, and Amazon's checks and reviewers notice. The reliable way is to remove the background and apply a digital white: bgclear's White preset produces exactly RGB 255.
Keep the product at 85% of the frame, shoot at the highest resolution you have (Amazon zoom wants 1600 px+ on the long side), and use JPG for the smallest upload. Step-by-step: Amazon listing background remover; sellers with large catalogues can automate it with the API.
