Image requirements (checked October 2026)
- Main images should show the item on a seamless white background (RGB 255, 255, 255). Images of larger items may show the item in an expected environment. [1]
- Crop the item as close as possible to the image frame and avoid excessive background space. Don't enlarge small images to fill space; it reduces quality. [1]
- The main image shouldn't contain watermarks, your name or your logo, and can't show accessories that aren't included with the item. [1]
- No image should include claims or promotional language, or Walmart or other retailer/marketplace logos or names. [1]
- All images must be in focus, professionally lit, and match the product name and its key attributes. No duplicate images on the item page. [1]
- Images shouldn't include languages other than English, and AI-generated images must be truthful, accurate and not misleading. [1]
- Selling on Walmart Canada? Its separate guide recommends 2000 × 2000 px at 300 ppi, and seamless white (255, 255, 255) is the preferred main image background. [2]
Platforms change their rules; always confirm with the official source below before you list.
How to make one with SnapStudio
- Take the photo in soft, even light (a window on an overcast day is ideal). Fill most of the frame with the product and keep the whole item in shot.
- Open SnapStudio and drop the photo in. The background is removed in your browser; the image is never uploaded to a server.
- Pick a background (pure white #FFFFFF, any solid colour, or a soft gradient) and toggle the subtle shadow and lighting cleanup.
- Tick the export sizes you need and download the JPGs (plus a transparent PNG cutout) individually or as a ZIP.
SnapStudio doesn't have a dedicated Walmart preset yet. The closest fit is the Amazon export: a 2000×2000 px square JPG on pure #FFFFFF, which clears Walmart's 1500 px zoom minimum but is below the 2200 px in Walmart's spec. Free images carry a small watermark, which Walmart doesn't allow on a main image, so use a paid pack or plan for the files you list. Selling on Amazon too? See the Amazon main image requirements; the two rule sets are similar.
