Download the preset dimensions as CSV to keep with your catalog checklist. These are CatalogCut export presets; use the official requirements below to review the finished image. For a local source check and JPEG export, try the marketplace photo checker.

The table below is a practical starting point, reviewed against the linked first-party guidance on September 14, 2026. Marketplace and category policies change, so use the source link before publishing a large catalog or relying on a rule for compliance.

A platform policy is not the same as a recommendation for every product. Category, product type, and theme rules can be stricter, so keep the original capture and create destination-specific exports from it.

A reliable workflow begins with a sharp, well-lit original that accurately shows the product. Preserve that original, then create a separate export for each destination instead of forcing one crop and background across every marketplace.

• Size: meet the marketplace minimum from a genuinely detailed source; upscaling cannot recreate missing detail.
• Crop: make the full product recognizable in the first thumbnail and leave enough room for channel-specific crop behavior.
• Background: use a compliant primary image where the marketplace requires white, then use contextual secondary images only where permitted.
• Accuracy: show the actual item, included accessories, and material condition rather than a misleading composite or placeholder.

JPEG is a safe default for many marketplace uploads, but it is not the only supported format. Use the marketplace's documented list rather than assuming that a modern web format will upload everywhere.

Shopify's documented product-media types can change, so check the linked documentation. For Etsy, confirm the current accepted formats and transparency behavior in its linked image guidance. Amazon and eBay each publish their own accepted-format lists. Verify the final export in the seller workflow before batch uploading.

Run this short check on the exported file, not only on your editing canvas:

1. Open the final file and confirm its pixel dimensions, format, and file size.
2. View the first image at thumbnail size: can a buyer identify the exact product immediately?
3. Inspect edges, fine detail, reflections, and shadows at 100% zoom.
4. Check required background color and remove prohibited text, watermarks, borders, or unrelated props.
5. For used or imperfect products, include accurate condition views rather than hiding flaws.
