Walmart image requirements checker
Walmart's image spec is the strictest of the four: 2000 x 2000 px at 300 ppi for zoom, a 500 x 500 px minimum that unpublished listings below it, and a hard 1 MB file cap. Check any photo locally in your browser.

How to use it
Walmart enforces its minimums
Walmart is explicit about enforcement: items whose primary image falls below the 500 x 500 px minimum are unpublished automatically, so the size row above is not advisory. The target to aim for is 2000 x 2000 px at 300 ppi, which activates zoom. The 1 MB file cap is the other hard number — it is tighter than Amazon's and eBay's, so exports need real compression. This tool reads your file's dimensions and size instantly. If a row fails, re-export at the true source resolution and watch the file size as you lower JPEG quality to fit under 1 MB.

Practical guide
Fit Walmart's 1 MB cap without losing zoom
- Export at 2000 x 2000, then compress. A 2000 px JPEG at quality 75–85 usually lands under 1 MB. Check the file-size row and lower quality only until it fits.
- Never upscale to hit 2000 px. Walmart warns against enlarging low-resolution images — quality drops and zoom looks soft. Re-shoot or re-export at the source resolution.
- Watch PNG bloat. PNG photos at 2000 px can exceed 1 MB easily. Convert product photos to JPEG; keep PNG for flat graphics.
- Host images on a real URL. Walmart pulls images from URLs that must end in an image extension (.jpg, .gif) and load as images, not HTML pages.
Walmart's enforcement is automated and blunt: items whose primary image falls below the 500 x 500 minimum are unpublished automatically, with the status change reason recorded in Seller Center as "an image for your item does not meet minimum required resolution." The fix path is just as mechanical — re-ingest the item with a valid image and it republishes. Because the 1 MB cap is far tighter than other marketplaces, the export pipeline matters: a 2000 x 2000 JPEG at quality 75–85 usually fits, while the same image as a PNG often does not. Check every export with this tool before upload, and Walmart image issues stop costing you listing time.
Walmart's spec also covers swatches and secondary images: swatch images are recommended at 100 x 100 pixels at 72 ppi, and the same 500 x 500 minimum applies to primary images, while secondary images share the format and file-size rules. Because Walmart pulls images from URLs, hosting matters too — the URL must end in an image extension such as .jpg or .gif and load as an image file rather than an HTML page. If you host images on Dropbox or similar services, use the public view-only link that serves the file directly. Between the resolution rows, the 1 MB cap and the URL rule, the most reliable habit is to check every export here before uploading, then confirm the hosted URL opens as an image in a plain browser tab.
