Main image rules on Amazon
Amazon treats the main image differently from every other photo on the listing. It must show only the product being sold, on a pure white background (RGB 255, 255, 255), with the product filling about 85% of the frame. Text, logos, watermarks, borders, and accessories that are not included are not allowed in the main image, and listings that break these rules can be suppressed from search.
The image must be at least 1000 px on its longest side for zoom to work. Many sellers use 2000 × 2000 px squares because they look sharp on high-resolution screens and match the square tiles Amazon uses in search.
Getting the 85% framing right
If the product is too small in the frame, it looks tiny next to competitors in search results. If it touches the edges, it can look cramped and may be cut off on some layouts. A good starting point is to crop so the longest side of the product nearly reaches the frame, leaving a thin, even margin of white.
Use the adjust button on each photo to zoom in until the product fills the square, then drag it to the centre. For products that are much wider than they are tall, such as keyboards, choose the fit option so the whole product stays in frame on a white background.
Secondary images
Amazon allows several additional images, and these are not held to the white-background rule. Use them for lifestyle photos that show the product in use, close-ups of materials and features, a photo with a hand or a common object for scale, what is included in the box, and a simple dimensions graphic.
Keep secondary images the same size as the main image, ideally square, so the image gallery and zoom behave consistently. Exporting every image for a listing in one batch at 2000 × 2000 px is the simplest way to achieve that.
Background note
This tool crops, resizes, and can add a white background around a photo when you choose the fit option, but it does not remove an existing background. For the main image, photograph the product on a white sweep or light box, or remove the background first, then use this tool to size and frame the result. Check the corners of the final image: an off-white or grey background is one of the most common reasons a main image is flagged.
