Walmart: 1,000px floor, 2,200px recommended for the hero image

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quality floor; 1,500 px is the minimum for zoom-on-hover, and primary images under 500×500 px are automatically unpublished.

Walmart: hero image must use a pure white background

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.

Walmart: hero image must be JPG, PNG, or BMP

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.

Walmart: hero image must be 5 MB or smaller

Walmart's item setup pipeline rejects images larger than 5 MB. Most well-exported JPGs at 2,200 px land between 300 KB and 2 MB; PNGs can exceed the cap and must be optimized.
