Marketplace guide
Meeting the minimum size is only part of the job. What matters just as much is the 1:1 frame, how the product sits inside it, how clean the background looks, and whether the final image stays readable in search and gallery views. This page turns that into a usable Picmu workflow.

Benefits
A practical Walmart Marketplace guide covering 2200 x 2200, 1:1, JPG, and the mistakes that weaken listing photos.
Instead of a generic resize flow, the page starts from 2200 x 2200, the 1:1 frame, and the export treatment that usually fits the listing best.
Use RGB color format.
You can test background treatment, whitespace, and file naming locally in the browser without pushing product photos into a remote queue.
Page setup

Page defaults
The practical starting point here is 2200 x 2200 with the 1:1 frame, so you can judge the listing before the final export rather than after it.
A dependable export set here is JPEG, JPG, PNG, BMP. File-size guidance: keep the result under 5 MB.
Use a clean white background for the primary image.
Recommend at least four images per listing.
Capability notes
This preset is marked verified as of 2026-04-11 based on the rules documented in this project.
Picmu can judge dimensions, format choice, background treatment, crop risk, and thumbnail strength from the file and the current settings. Real uploader acceptance should still be checked with one reference file.
Match the product name, type, and key attributes.
Tradeoffs

Recommend at least four images per listing.
Accepted formats like JPEG, JPG, PNG, BMP matter, but the frame, background, and product fill usually do just as much work.
