Amazon Main Image Checker
"Your main image does not have a pure white background" — on an image that looks perfectly white. Drop it here and see the actual RGB values Amazon's scanner sees.
🔒 Your data never leaves your browser — images are read and measured in this tab.
Why a white image fails a white-background check
Amazon's requirement is not "white" — it is RGB 255,255,255, checked by an automated scan. A background at 250,250,250 is indistinguishable to the human eye and to every reviewer you ask, and it still fails. The usual culprits:
- A studio shot where the backdrop was lit to "near white" rather than blown out to pure white
- An editor's default "white" swatch that is not actually #FFFFFF
- JPEG compression artefacts around the product edge
- A colour profile applied on export that shifts every value by one or two levels
- A soft drop shadow or vignette bleeding into the background
This tool samples eight points around the edges and shows you the numbers, plus a swatch of your background next to true white. If you cannot see the difference — that is the point.
What gets measured
| Requirement | Value |
|---|---|
| Longest side, minimum | 1000 px (below this, zoom is disabled) |
| Longest side, recommended | 1600 px |
| Maximum side | 10000 px |
| Background | RGB 255,255,255 |
| Product fills | 85% of the frame or more |
What this tool cannot tell you
It measures pixels; it does not look at the picture. Text, logos, watermarks, borders, inset images, mannequins, props, and whether the photo actually shows the product you are selling are all main-image violations that need a human or a vision model. The frame-fill number is an estimate from the bounding box of non-white pixels, not Amazon's own calculation.
A clean report here means the measurable requirements are met — not that the image will be approved.
Every check this tool runs (12 rules)
Size & file
IMG-S01 Longest side under 1000 px
The longest side must be at least 1000 pixels. Below that, the zoom function is disabled — and listings without zoom convert measurably worse. Images well under the limit are rejected outright.
Fix: Re-export at a higher resolution from the original file. Upscaling a small image does not add detail and usually looks worse than the original.

IMG-S02 Smaller than the recommended 1600 px
The image meets the minimum but sits below the 1600 px recommended for the best zoom experience.
Fix: Export at 1600 px or larger on the longest side where the source allows it.

IMG-S03 Side over 10000 px
Neither side may exceed 10000 pixels.
Fix: Downscale the image.

IMG-S04 Unusual aspect ratio
Main images are displayed in a square frame. A very tall or very wide image gets letterboxed, leaving the product small on screen even when the file itself is large.
Fix: Crop or pad to a square (1:1) canvas with the product centred.

IMG-S05 Transparent background
The image has transparent pixels. Transparency renders as whatever colour the surrounding page uses, so an image that looks white in your editor may not be white on the marketplace.
Fix: Flatten the image onto a solid pure-white background before exporting.

Background
IMG-B01 Background is not pure white
The main image background must be pure white — RGB 255,255,255. This is checked by an automated scan, and off-white backgrounds are the single most common cause of main-image rejection. The human eye cannot tell 250,250,250 from 255,255,255, which is exactly why sellers get caught.
Fix: In your editor, set the background layer to exactly #FFFFFF rather than "white-ish", and export without a colour profile that shifts the values.

IMG-B02 Background is white but close to the threshold
The sampled background is very near pure white but not exactly 255 everywhere — often the result of JPEG compression artefacts or a soft vignette. It may pass today and fail after a re-encode.
Fix: Fill the background with pure white and export as a high-quality JPEG or a flattened PNG.

IMG-B03 Background varies across the edges
Sampled corners and edges differ from each other — typically a gradient backdrop or a shadow falling on the background. Automated scans read this as a non-white background even when parts of it are pure white.
Fix: Remove the gradient or shadow from the background; keep product shadows inside the product area only.

Framing
IMG-F01 Product fills less than 85% of the frame
The product should occupy at least 85% of the image frame. This is an ESTIMATE: we measure the bounding box of the non-white pixels, which is not the algorithm Amazon uses. Treat it as a strong hint, not a verdict.
Fix: Crop closer to the product, leaving only a small margin.

IMG-F02 Product touches the edge of the frame
Non-white pixels reach the border of the image. The product is cropped or has no margin at all — either way it looks cut off in the listing grid.
Fix: Leave a small even margin around the product.

IMG-F03 Image appears blank
Almost every pixel is white — there is no product visible. Usually an export of the wrong layer or an empty canvas.
Fix: Check that you exported the right file.

IMG-F04 What this tool cannot check
Text, logos, watermarks, borders, inset images, mannequins and whether the product shown is the product sold — all of these are Amazon main-image violations that require looking at the picture, not measuring it. This tool measures pixels only, so a clean report here is not a guarantee of approval.
