What counts as a pure white background on Amazon?

Amazon's main image policy requires a pure white background - RGB (255, 255, 255) - so the background blends seamlessly with the search and detail pages. This checker samples the edge pixels and reports how close they are to true white, plus a pass, review, or fail verdict per marketplace.

Is my image uploaded to a server?

No. The image is decoded and analyzed entirely in your browser with the Canvas API. Nothing is uploaded, stored, or sent anywhere - close the tab and nothing remains.

Which marketplaces require a white background?

Amazon, Walmart Marketplace, TikTok Shop, Cdiscount, and Zalando packshots require a white or pure-white background. eBay, Etsy, Shopify, Meta, Mercado Libre, and Newegg treat it as optional - the checker grades all of them.

How does the white background check work?

It samples the outer edge band of the image (where the background sits), measures the share of pure-white and near-white pixels, detects the dominant background color, and rates rejection risk using the same logic as the CatalogPrep marketplace compliance audit.

My background looks white but it fails - why?

Cameras and lighting often produce off-white or grey casts (245,245,247 instead of 255,255,255), JPEG compression halos, or soft shadows near the product. These are invisible on screen but fail strict marketplace review. Rebuild the background to fix it.

How do I fix a background that is not white enough?

Use the CatalogPrep background remover to cut out the product and place it on a clean pure-white canvas, or run a marketplace prep workflow that resizes, frames, and exports a listing-ready white-background image.
