Walmart Marketplace Image Requirements (2026): Size, Main Image Rules and a Checklist

Walmart Marketplace image requirements: the main image must be a square (1:1) JPEG, PNG or BMP on a seamless pure white background (RGB 255, 255, 255), with no logos, watermarks or text. Walmart recommends 2200×2200 pixels, needs at least 1500×1500 for zoom, and caps files at 5 MB. Plan on at least four images per listing.

Walmart's rules look like Amazon's, with two differences that trip up sellers moving between the two: a larger recommended size and a smaller file size cap. Images also feed into Walmart's Listing Quality score, which affects how visible your items are. This guide covers the main image rules, sizes and files, what secondary images can show, common rejection reasons, and a checklist.

What size should Walmart product images be?

Walmart recommends square images of 2200×2200 pixels, with 1500×1500 as the minimum for the zoom feature. Images below about 500 pixels on a side are widely reported to be suppressed or unpublished. Since a 2200-pixel JPEG easily fits under 5 MB, there's no reason to go smaller.

Walmart Marketplace's image size, format and main image rules were checked in October 2026. Marketplaces change their rules, so confirm the current requirements in your seller dashboard before you upload a large batch.

Two numbers catch Amazon sellers out. Amazon's common 2000×2000 export is slightly under Walmart's 2200 recommendation, though still above the zoom minimum. And Amazon accepts files up to 10 MB, while Walmart stops at 5 MB, so a high-quality PNG that works on Amazon can be rejected on Walmart. Export JPEGs and you'll rarely hit the cap.

Can I just upscale small images to 2200 pixels?

Stretching a small image in a basic editor makes it bigger but blurrier, and Walmart's guidance warns against low-quality enlargements. AI upscaling that adds real detail is better, but the best fix is a sharp, well-lit source photo.

What are Walmart's main image rules?

The main image must show the product alone on a seamless pure white background, with nothing added. It is the image shoppers see in search and on category pages, and the one most often rejected.

• Seamless white, RGB 255, 255, 255. No gradients, textures or cream tones, and no visible horizon line between floor and wall.
• Only the product being sold. No props and no accessories that aren't included.
• No logos, watermarks, your store name, overlays or text. Branding printed on the product is fine.
• The front of the product, fully visible and not cropped.
• Product fills the frame. Crop so the product takes up most of the square; large empty margins look weak in search.
• Accurate. Same color, variant and parts the buyer receives.

What can Walmart secondary images show?

Secondary images can use other clean backgrounds, lifestyle settings and text, as long as they stay accurate. They are where you explain the product and answer questions before a shopper asks.

Avoid claims you can't support on infographics, such as "#1 rated" or health claims, and don't show competitor products or prices.

Why does Walmart reject product images?

When an image fails, check Seller Center's item errors and your Listing Quality dashboard. Fixing images is often the quickest Listing Quality gain available.

Pre-upload checklist

1. The image is square, 2200×2200 px (never below 1500).
2. The file is JPEG, PNG or BMP and under 5 MB.
3. Main image corners read 255, 255, 255, with no gradient or horizon line.
4. The product fills most of the frame and nothing is cropped off.
5. No logos, watermarks, text, props or accessories that aren't included.
6. Each color or variant has its own main image.
7. Files are named with the GTIN.
8. At least four images in total, each showing something different.

Making Walmart images with AiArter

AiArter cuts the product out of your own photo and changes only the background, so labels, colors and shape stay true.

• White main image (4 credits). Pure white RGB 255, 255, 255, product centered and filling about 85% of a 2000×2000 frame, with an optional soft shadow. That clears Walmart's 1500 px zoom minimum with room to spare.
• Upscale (3 credits) a sharp but small source photo (it increases resolution four times) before you cut it out, so it clears the zoom minimum.
• Lifestyle scenes (8 credits) from presets like Living room, Wooden table, Bathroom shelf or Outdoors, or a scene you describe.
• Infographics. Place the cut-out in a design template and add feature callouts.
• Whole catalogs. The bulk background remover processes up to 50 photos per batch with one ZIP download; failed photos aren't charged.
• Titles and descriptions. The listing copy writer drafts them from your product details.

Check file sizes after export; a JPEG at 2200 px is almost always under 5 MB. Our guides to Amazon product image requirements, making a background pure white and upscaling product photos go deeper on each step, and removing backgrounds in bulk covers large catalogs.

Getting a good source photo

Start sharp and you won't need to fix much. Shoot near a window in soft daylight, tap to focus on the label, keep the camera level with the product's front, and leave a margin so you can crop to square without cutting anything off. Shoot every variant in the same session so colors match across the listing.

Frequently asked questions

What size should Walmart product images be?

Walmart recommends square images of 2200×2200 pixels. The minimum for zoom is 1500×1500 pixels. Files must be JPEG, PNG or BMP and no larger than 5 MB.

Does Walmart require a white background?

Yes, for the main image. It must be a seamless pure white background, RGB 255, 255, 255, with no gradients or textures. Secondary images can use other clean backgrounds or lifestyle settings.

How many images should a Walmart listing have?

At least four is the common recommendation, and six to eight is better for most products. Mix a white main image with alternate angles, close-ups, a lifestyle scene and an infographic.

What file size does Walmart allow for images?

Up to 5 MB per image. That is half of Amazon's limit, so large PNG files can fail. Exporting JPEG at high quality usually keeps a 2200-pixel image well under the cap.

Can I use my Amazon images on Walmart?

Often yes, since both require a pure white main image with no text. Check that each file is under 5 MB and square, and consider upscaling to 2200 pixels for the best zoom.

Can Walmart main images have logos or text?

No. Walmart's main image can't include logos, watermarks, your store name, overlays or text. Branding printed on the product itself is fine.
