Upload your main product image. The checker tests it against Amazon's published main-image guidelines and explains each result: background, fill, size, file type, color mode and file size.


An Amazon main image passes when the background is pure white (RGB 255, 255, 255), the product fills at least 85% of the frame, the longest side is at least 1,000 px and the file is a JPEG, PNG, TIFF or GIF under 10 MB. This free checker tests all of that in your browser before you upload.

Checks follow Amazon's main-image guidelines as commonly published: pure white background, product filling about 85% of the frame, 1000 px or more for zoom, JPEG, PNG, TIFF or non-animated GIF, and under 10 MB. Some categories have their own rules, so check the style guide for yours in Seller Central. The checker can't see props, added text, logos or watermarks.
