Background

Amazon: Amazon's product detail and search pages render against a white surface; the main image background must be RGB 255,255,255 so the product appears to float on the page.

Walmart Marketplace: Walmart's item image guidelines require the hero image background to be pure white (RGB 255,255,255). Non-white backgrounds delay item setup and may suppress the listing.

Resolution & dimensions

Amazon: Images below 1,000 px on the longest side disable Amazon's zoom feature and reduce conversion. 2,000 px is the recommended size for zoom-quality.

Walmart Marketplace: Walmart recommends the hero (primary) image at 2,200×2,200 px and treats 1,000 px per side as the practical quality floor; 1,500 px is the minimum for zoom-on-hover, and primary images under 500×500 px are automatically unpublished.

Subject framing

Amazon: The product must take up at least 85% of the image area on Amazon's main image to ensure it is easily recognizable in search results.

Walmart Marketplace: No published rule tracked.

Text, watermarks & overlays

Amazon: Amazon's main image must show only the product. Any text overlay, brand logo, promotional badge, or watermark on the main image triggers suppression.

Walmart Marketplace: No published rule tracked.

File format & size

Amazon: No published rule tracked.

Walmart Marketplace: Walmart accepts JPEG/JPG, PNG, and BMP for product imagery. GIF, WebP, AVIF, and HEIC are not supported and will fail item setup ingestion. JPG is preferred for photographic content.

AI-image disclosure

Amazon: Amazon permits AI for photo enhancement (background removal, color, lighting, resize), but the main image must truly represent the actual product. AI-fabricated or misleading main images risk suppression, and AI use must be disclosed. Detection is rolling out through 2026.

Walmart Marketplace: No published rule tracked.
