An Amazon MAIN product image is best at 2000×2000 pixels, a 1:1 SQUARE, and that is what this preset targets in 2026. The hard minimum is 1000 px on the LONGEST side, because that is the threshold that switches on Amazon’s click-to-zoom; Amazon recommends 1600 px or more, and 2000–3000 px on the longest side is the current best practice. Zoom is worth chasing — listings that fail to enable it can convert 15–25% worse, since shoppers can’t inspect detail like texture, stitching or print. A square 1:1 image also displays cleanly in Amazon’s search grid and gallery. The ceiling is 10,000 px on the longest side and a 10 MB file, with aspect ratios up to 5:1 allowed for secondary images. This tool has a one-tap Amazon preset that exports at exactly 2000×2000 with a live square preview, and it downscales a large source with pica’s Lanczos filter so a 2000×2000 photo stays sharp enough to make zoom worthwhile.

Amazon’s MAIN image (the first, and the one shown in search) has strict rules that an automated scan enforces. The background must be PURE WHITE — exactly RGB 255,255,255, which Amazon renders as seamless with the site — and it is unforgiving: off-white (250,250,250), light grey (240,240,240) or even a single channel at 254 can be flagged as non-compliant and get the image suppressed. The product must fill at least 85% of the frame, centred, with a small even margin so it doesn’t touch the edges. The main image may contain NO text, logos, watermarks, borders, gradients, badges or inset images, and it must be a real photograph of the actual product — no illustrations, renders or mockups. Save it in sRGB, because CMYK shifts colour in browsers. Only the MAIN image carries these rules; the other slots (up to 9 images total) can hold lifestyle shots, infographics and comparison images on any background. This tool sets the canvas to exactly 2000×2000 and, in CONTAIN mode, can pad with white (255,255,255) to match the spec.

Partly, and it is worth being precise. If your photo is already shot on white but isn’t square, switch to CONTAIN mode and set the padding colour to pure white (RGB 255,255,255): the tool fits your whole photo inside a 2000×2000 canvas and fills the letterbox bars with white, so the finished square matches Amazon’s main-image background exactly. What the tool CANNOT do is replace a coloured, grey or busy background that sits BEHIND the product itself — that is background removal, a different operation, and Amazon needs pure white right up to the product edge, not just in the padding. So for a clean main image, start from a photo already on a white or easily-removed backdrop (or run it through a background remover first), then use this tool to hit exactly 2000×2000 and square it up with a white pad. The tool also can’t measure the 85% fill or otherwise certify compliance; it sizes and pads the canvas, and you frame the product.

Nothing is uploaded. When you choose an image the tool creates a local object URL, decodes it, crops and composites it on an in-page canvas, and downscales it with pica — all on your device. There is no server, API, database or tracking anywhere in the processing path, so your image never leaves the browser. Object URLs are revoked when you reset or replace the image, the tool works offline once cached, and closing the tab discards everything. The only optional network use anywhere on the site is consent-gated advertising, which never sees your image. You then upload the finished 2000×2000 image to Amazon Seller Central yourself, so an unreleased product photo or an unlaunched listing stays private until you publish it.
