Walmart Marketplace Listing Photo Studio

Meeting Walmart's square, large primary image from a phone photo

Walmart Marketplace publishes strict rules for the primary image: square, a pure white background, at least 1,500 by 1,500 pixels (ideally about 2,200) and under 5 MB, in sRGB. Plan backward from those numbers. The result here keeps your upload's shape, so crop the photo to a square before generating, and make sure the cropped square is at least 1,500 pixels wide.

This editor prepares very large uploads at 2,048 pixels on the long side, which clears Walmart's minimum but not its ideal size; the free download is web size, so the primary image needs the original resolution, unlocked with Premium or one credit. If you want to reach the larger figure, enlarge the finished file and check that edges and printing stay clean.

Because a generated white may not be exactly pure white, the safest primary image is a true cut-out on white, while this page suits the secondary images that show use and context. Run each file through the listing image checker before upload; it flags problems against the published requirements so you can fix them before Walmart's own review sees the file.
