Fix Walmart white background rejects
September 2026
Walmart Marketplace main images usually need RGB 255,255,255 on a clean square canvas. Off-white sweeps, halos, and transparent PNGs fail the same way they do on Amazon.
Walmart white-background failures
| Failure | What to hit |
|---|---|
| Off-white sweep | RGB 255,255,255 / #FFFFFF |
| Cutout halo | Re-fill canvas after remove-bg |
| Transparent PNG | Flatten onto white before upload |
| Grey fringe after JPEG | Re-check the exported file |
1. Diagnose the background
Run the Walmart checker on the rejected main image. If white fails, the export is not true #FFFFFF.

2. Fill white on-device
Cut out, fill #FFFFFF, and re-export. Category exceptions still live in Seller Center.
Before you re-upload
- Background 255,255,255
- No halo or shadow
- Flattened JPG/PNG
- Re-check after compression
