I assumed Walmart Marketplace image requirements were the same as Amazon's. White background, high resolution, product fills the frame. Same rules, different platform.
I was wrong. Eight of my first 20 listings got suppressed within 48 hours. Walmart's requirements overlap with Amazon's but have key differences that caught me off guard.
The Requirements
Main Image
- Pure white background (RGB 255,255,255) — same as Amazon
- Minimum 1000×1000 pixels (Amazon is technically 1000 but recommends 1600+)
- Product must fill 80-100% of the frame
- No text, watermarks, logos, or borders
- No props or accessories not included in the purchase
- JPEG or PNG format
Secondary Images
- Up to 10 images total (including main)
- Can include lifestyle, infographic, and detail shots
- Text overlays allowed on secondary images
- Same resolution requirements
The Differences From Amazon
Stricter on image quality. Walmart's automated checker flags blurry images, low contrast, and poor lighting more aggressively than Amazon's. Two of my suppressions were for "image quality" on photos that Amazon accepted without issue.
Different fill requirements. Walmart wants 80-100% fill. Amazon wants 85%+. The difference is small but Walmart enforces the lower bound more strictly — I had a listing suppressed for a product that filled about 75% of the frame.
Variant image requirements. Walmart requires that each variant (color, size) has its own unique main image. Amazon recommends this but doesn't always enforce it. Walmart will suppress your listing if the blue variant shows a red product.
No lifestyle main images. Some Amazon categories allow lifestyle main images (like Home & Kitchen). Walmart requires white background for ALL main images, no exceptions.
What Got My Listings Suppressed
-
Image quality too low (3 listings) — Photos that were slightly soft/blurry. They looked fine on my phone but didn't meet Walmart's sharpness threshold.
-
Background not pure white (2 listings) — Same issue as Amazon. My background was close to white but not 255,255,255.
-
Product fill too low (2 listings) — Too much white space around the product.
-
Variant mismatch (1 listing) — My blue variant was showing the black product image because I hadn't uploaded variant-specific images.
The Fix
For background and fill issues, I reprocessed all images through pic1.ai with the white background preset and 85% fill target. This guaranteed pure white backgrounds and proper product sizing.
For the quality issues, I re-shot the products with better lighting and at maximum phone resolution (48MP). The higher source resolution gave Walmart's checker more pixels to work with.
For the variant issue, I shot each color variant separately and uploaded unique images for each.
After fixing all issues, all 20 listings were approved within 24 hours.

|---|---|---|
| Background | Pure white (255,255,255) | Pure white (255,255,255) |
| Min resolution | 1000px (1600+ for zoom) | 1000×1000 |
| Product fill | 85%+ | 80-100% |
| Max images | 9 | 10 |
| Variant images | Recommended | Required |
| Quality check | Moderate | Strict |
| Main image style | White BG (most categories) | White BG (all categories) |
My Walmart Image Workflow
Same as my Amazon workflow with two additions:
-
Higher source resolution. I shoot at 48MP instead of the default 12MP to ensure Walmart's quality checker is satisfied.
-
Variant-specific images. Every color/size variant gets its own photo session. No sharing images between variants.
The extra effort is minimal — maybe 10 minutes more per product — and prevents the frustration of suppressed listings.
