ResultTechnical comparison, not approval

One source, four different checks

The comparison separates official thresholds, recommendations, OpenFileTools working targets, and automated estimates. A green technical result is not a promise that a marketplace will approve the listing.

  • Amazon: zoom readiness, stronger longest-side target, and approximate white-border analysis.
  • Etsy: first-photo threshold and both-dimensions recommendation.
  • eBay: longest-side minimum, working target, and file size.
  • Shopify: upload limits plus square-image guidance.
