How SellerImg Presets Are Chosen
Every preset separates what a platform officially documents from the format, size and quality SellerImg selects as a practical batch-processing starting point.
Last reviewed August 4, 2026 · Content owner: AnthonyHow the review works.
Anthony checks first-party platform documentation, records the applicable market, and avoids describing a SellerImg convenience setting as a platform requirement. A preset is then tested with real product photography for dimensions, actual byte size and visible detail.
Platform rules can change between reviews. The official links below remain the source of truth, and category-specific requirements take priority over a general preset.
