Walmart Image Checker

Walmart Marketplace expects large, professional product images, and the primary image generally needs a pure white background with the product filling most of the frame. This free checker estimates your image dimensions, square framing, and crop risk in the browser so you can catch obvious problems before listing.

Walmart typically recommends a long side around 2000px for zoom and clean, single-product main images without text or props. This tool reads pixel size and overlays crop guides; it cannot verify background color precisely or read text, so confirm against current Walmart image guidelines.

Processing runs locally with the canvas API and your photos are not uploaded. A good next step is to square the image, resize it to a large dimension, and clean the background to white before uploading.
