A fact-checked starting point for product-image size, format, background, and gallery requirements across major marketplaces. Always check the linked marketplace policy before a large upload.

TL;DR

Use the marketplace's current policy, not a one-size-fits-all preset. Start with a high-resolution original, then export the correct size, format, background, and crop for the channel where it will be listed.

Marketplace image standards at a glance

The table below is a practical starting point, verified against the linked first-party guidance on August 1, 2026. Marketplace and category policies change, so use the source link before publishing a large catalog or relying on a rule for compliance.

Platform	Current starting point	Source
eBay	At least 500px on the longest side; about 1600 × 1600px recommended; up to 24 photos; files up to 12MB.	Official guidance
Amazon	For MAIN images: pure white background. Use at least 1000px on one side for zoom; category rules can add requirements.	Official guidance
Etsy	At least 2000px wide is recommended. Use a horizontal or square first image and leave room for thumbnail crops.	Official guidance
Shopify	Up to 5000 × 5000px or 25 megapixels and under 20MB. Shopify says 2048 × 2048px usually displays best for square product images.	Official guidance
TikTok Shop (US)	At least 600 × 600px, up to nine images. Use an accurate main image without added text, borders, or watermarks.	Official guidance
Walmart Marketplace	Primary images need a seamless white RGB(255,255,255) background and no added graphics, overlays, text, logos, or watermarks.	Official guidance

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.

Start with one high-resolution master, then make destination exports

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.

Choose the file format by destination, not by habit

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 supports a broad set of product-image formats, including PNG, JPEG, WebP, HEIC, TIFF, GIF, BMP, PSD, and SVG. Etsy supports JPG, GIF, PNG, SVG, and HEIC—but Etsy says transparent PNG areas appear black. Amazon and eBay each publish their own accepted-format lists. Verify the final export in the seller workflow before batch uploading.

A five-minute image QA check before you upload

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

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

For a fuller pre-publish review, use the background-removal QA checklist and the white-edge troubleshooting guide.

Frequently asked questions

What is the best ecommerce product image size?

There is no universal best size. Keep a high-resolution original, then use the platform's current requirements for the final export. For example, Shopify says 2048 × 2048 pixels usually displays best for square product images, while eBay recommends about 1600 × 1600 pixels.

Can I use the same product image on every marketplace?

You can begin from the same original, but do not assume the same finished export works everywhere. Marketplace rules differ on crop, background, dimensions, formats, and what can appear in a primary image.

Should marketplace product images have a white background?

Use white when the marketplace requires it for the primary image, such as Amazon, Walmart Marketplace, and TikTok Shop's current US policy. Elsewhere, check the platform's policy and make sure the product remains clear and accurately represented.

Should I use transparent PNG for Etsy?

No. Etsy's current help guidance says transparent PNG is not supported and transparent areas appear black. Export a compatible image without transparency for Etsy listing images.
