Walmart Marketplace Listing Images

Walmart's image rules look like Amazon's from a distance and behave differently at the point of upload. Both want a square frame, pure white behind the product, and nothing written on the main image. Where they part company is what happens when you miss: Amazon quietly drops the zoom feature, while Walmart's own guidelines say an item whose main image falls below 500 x 500 pixels is unpublished outright. That, plus a file-size ceiling most 2160px PNGs breach, is what actually costs sellers listings.

The numbers Walmart publishes, including the ones that disagree

Walmart documents its image specs in more than one place, and the places do not match. This is worth stating plainly, because most guides pick whichever figure suits their headline and present it as the rule.

The resolution the specs converge on is a square file of 2000 pixels or more, saved as JPEG small enough to clear 1 MB. That satisfies both documents at once and leaves nothing to argue about with a rejection notice. The Listing Quality dashboard, separately, describes the image checks it runs as quantity, zoom resolution at 1000 pixels or above, overall resolution at 500 pixels or above, whitespace ratios and placeholder detection — a third set of thresholds, and the one your score is actually measured against.

The main image: same white, stricter framing

Walmart calls the main image the silo shot and wants the product on a seamless white background at RGB 255,255,255, front-facing and slightly angled to the right, with roughly a 2.5% white border so the product does not touch the frame edge. Text, logos, watermarks, overlays, borders, coupons and any accessory that is not in the box are all prohibited there.

The angle instruction is the one Amazon sellers miss. Amazon has no house angle; Walmart states one. If your existing main image is a dead-on front elevation it will pass, but a three-quarter view rotated to the right is what Walmart's own documentation asks for.

What Listing Quality actually counts, and what nobody can tell you

Walmart scores listings rather than merely admitting them. The Listing Quality dashboard splits into three groups: Content & Discoverability, Offer, and Ratings & Reviews. Images sit inside the first, next to item name, description and key features.

What Walmart does not publish is how much each part weighs. Its own documentation says the three categories are not equally evaluated and that the algorithm differs across product categories. So the figures circulating in seller blogs — images are 15% of content quality, content is 40% of search weight — should be read as third-party estimates, not published facts. The actionable part is the checklist, not the percentage: enough images, above the zoom threshold, above the resolution floor, sensible whitespace, no placeholders.

What carries over from an Amazon set, and what does not

That last row is the one that silently breaks uploads. A 2160 x 2160 PNG with a photographic background routinely lands between 3 and 6 MB, which clears the 5 MB figure on one Walmart page and fails the 1 MB figure on the other. Export the same artwork as JPEG at quality 85 and a typical listing image lands well under 1 MB with no visible loss at listing scale.

Getting a Graflio set onto Walmart

Graflio reads an Amazon ASIN or listing URL, not a Walmart item page, so the research pass runs against your Amazon listing and its reviews and the design carries across. The studio canvas is square, and studio exports are 2160 x 2160, comfortably above every Walmart threshold. Generated gallery images arrive at 1024 pixels; that clears Walmart's 500 px floor and the dashboard's 1000 px zoom check, but it is below the 2000 px the Item Image Guidelines ask for, so open the image in the studio and export at full size before uploading rather than pushing the generated file straight through.

One detail specific to Walmart's bulk and API paths: image URLs must point directly at an image file, not an HTML page, must be encoded without special characters or query parameters, and must use port 80, 443, 8080 or 8443. If you host your images on a CDN that appends a signed query string, that alone will fail the item feed even though the picture is perfect.

Which set to build first

If Amazon is your larger channel, build the Amazon set first and adapt it. The main image is the only real rework, the compliance rules are close enough that a set designed for Amazon rarely breaks a Walmart rule, and the reverse is not true: Walmart permits things in the gallery that a set designed for Walmart would carry into Amazon unexamined. If Walmart is your larger channel or your only one, build square at 2000 pixels or more, obey the silo framing on the main image, and treat everything in the gallery as fair territory for callouts, dimension diagrams and comparison charts. Either way, the thing to check before you upload is not the design. It is the pixel count and the file size, because those are what Walmart enforces automatically and without a message you will enjoy reading.

Common questions

What size should Walmart product images be?

Square, at least 2000 x 2000 pixels, saved as JPEG under 1 MB. That satisfies every figure Walmart publishes across its different documentation pages.

Does Walmart really delist items over image size?

Yes. Walmart's Item Image Guidelines state that items with a main image below 500 x 500 pixels are automatically unpublished.

Can infographics go on a Walmart listing?

In the secondary images, yes. The main image must stay a clean silo shot on pure white with no text, logo, watermark or border.

Do I need a separate design for Walmart?

Usually not for the gallery. You need a separate main image if yours is not a right-angled front view on white, and you need to strip any Amazon-specific reference, review count or badge from the rest of the set.

How many images should a Walmart listing have?

Walmart requires a main image on every item and counts image quantity inside its Listing Quality score without publishing a target number. Building the same four to seven images you would build for Amazon puts you comfortably past the point where quantity is the limiting factor.
