Rules come from Walmart Marketplace Learn, read 9 October 2026. Full list on the Walmart product image requirements guide; Amazon sellers can use the Amazon checker.
Frequently asked questions
Is my image uploaded?
No. The check runs in your browser on your device. The file is never sent to Blurbly or anyone else.
What does the checker test?
Walmart’s published numbers: at least 1500 × 1500 px for zoom (2200 × 2200 px listed), a 1:1 square, a seamless white (RGB 255) edge, JPEG/PNG/BMP and 5 MB or less. It also reports how much of the frame the product fills, for information only.
Why is product fill not pass or fail?
Walmart says to crop as close as possible and avoid excessive background, but it does not publish a percentage, so we do not invent one.
Does passing mean Walmart will accept the image?
No. It is an estimate from pixel data and file details. Walmart makes the final call and some categories have extra rules.
