Marketplace guide
Walmart Marketplace is not just about hitting a minimum size. The platform-safe result usually depends on the frame 1:1, the way the product sits inside it, how clean the background feels, and whether the export keeps the listing readable in search and gallery views. This page turns those rules into a practical Picmu setup.

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 tends to keep the listing safer.
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.
Route setup
The linked Picmu route opens with the Walmart Marketplace preset so you can test the frame, background, and safer export setup immediately.
Route 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.
The safer export set here is JPEG, JPG, PNG, BMP. File-size guidance: keep the result under 5 MB.
Primary image should be clean white background.
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.
Images should match product name, type, and key attributes.
Tradeoffs
Warn below 1500x1500 for zoom-oriented use.
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.
