Check your Amazon main image for a pure white background
Upload your main images → see the actual RGB values at the four corners and along each edge, whether any edge carries a frame or line, and whether a soft shadow band runs along an edge. We sample the four corners and an 8-pixel-deep band along each edge and compare against exactly 255, 255, 255 (tolerance 0); the band depth and the tolerance are our own settings, and edge sampling is our method, not Amazon's published wording.

Have a pure white background (RGB color values: 255, 255, 255) to create a consistent shopping experience for customers across search and product detail pages.
Applies to the MAIN image. The RGB value is stated exactly, and the pages we captured on 2026-09-19 state no tolerance band; we did not find one. This checker compares every sampled corner and edge pixel against that exact value and reports the readings; it changes no pixel of your file.
Non-white background — background colour trigger
Background must be pure white (RGB 255, 255, 255); a background that is not pure white, with minimal shadows around the product, is suppression trigger 1 of the 2 in the excerpt we captured on 2026-09-19
There is a background and it is not pure white (RGB 255, 255, 255) with minimal shadows around the product
The official wording joins the two triggers with OR, so either one on its own is enough; the excerpt we captured on 2026-09-19 shows these two — check the linked page for any further trigger. We quote the official sentence rather than paraphrase it, because the page does not say how much shadow is acceptable. This checker tests the colour trigger by comparing every sampled corner and edge pixel with exactly 255, 255, 255.
Non-white background — edge frame, line or border trigger
No visual frame, line or border on any portion of the edges of the image — trigger 2 of the 2 in that same excerpt
There is a visual frame, line, or border on any portion of the edges of the image
Second trigger of the same suppression reason, and the other trigger in the excerpt we captured on 2026-09-19. A thin outline left by a cut-out, or a faint line added around a white product so it stands out, meets this description even when every other background pixel is exactly white. This checker scans each edge for a line that runs continuously along that edge; the official wording also covers a line on only part of an edge, which this test may not flag.
Shadows
Shadows that run to the edge of the image frame, or that the product or human models cast against a backdrop, are not allowed
Shadows that run to the edge of the image frame or that the product or human models cast against a backdrop are not allowed.
This checker looks for a soft, desaturated shadow band running along an image edge; a dark or strongly coloured non-white area at the edge is reported by the pure-white readings on the rows above, not by this test. It cannot judge whether a shadow that stays inside the image falls on a backdrop; that part of the rule is for you to review.
Borders, colour blocks and graphics in the background
No borders, colour blocks or other graphics covering the product or in the background
No text, logos, borders, color blocks, watermarks, or other graphics covering the product or in the background.
This page bans borders "covering the product or in the background". The rule about a frame, line or border on the edges of the image is the Non-white background page's own wording; that is the one this checker tests. This checker looks for a border along the edges only; it does not look for text or logos.
Clothing category — main image background
Pure white background, hex #FFFFFF or RGB 255-255-255
Pure white background (hex #FFFFFF or RGB 255-255-255)
The clothing page states the same colour in hex and in RGB, and #FFFFFF is RGB 255, 255, 255, so the clothing page and the general Product image guide give the same colour. We do not claim anything about category pages we have not captured.
What this tool does
Sample the four corners and an 8-pixel-deep band along each of the four edges of every image and report the actual RGB values we find
Report the RGB value at each of the four corners and, for each edge, the share of pixels that are exactly 255, 255, 255 together with the mean and lowest RGB we found
Scan each edge for a continuous line, frame or border that differs from the pixels just inside it — Amazon's second trigger covers a frame, line or border on any portion of the edges, so a mark that covers only part of an edge may not be flagged here
Report whether a soft shadow band runs along an image edge — we look for a continuous run of near-grey pixels (low saturation, mid brightness) covering at least a twentieth of that edge. A dark or strongly coloured non-white area at the edge is reported by the pure-white readings above, not by this test

What it does not do
Change any pixel of your image — this page reads and reports only
Decide what Amazon's review will do with your image — we compare your pixels with the published rule and show the official wording next to the result
Check the 85% product-size rule, the text and logo rules, or the other suppression reasons — the 85% area rule applies to all product images — the official suppression list scopes Product too small to any image, not just the main image — while the Product image guide words it as “Show the product as 85% of the image”; the two wordings are set side by side on the product image fill ratio checker; the page on why Amazon suppressed a listing image lists the other suppression reasons. All three pages are linked below
Judge anything beyond the sampled edge band — the border test compares the outer ring with the pixels just inside it, so a shadow that stays more than 8 px in from the edge is not judged here
Upload your files anywhere
We only read your file and report what we measured. We do not alter the content of your photo. Files are processed in your browser and are not uploaded to a server.
The product must occupy at least 85% of the image area, making use of as much of the image space as possible without cropping the product or letting shadows run to the edge of the image.
How we handle it: Product Too Small does not limit the rule to the main image; treat 85% as applying to all product images. Not tested by this checker — the product image fill ratio checker sets both wordings side by side.
Numbers you may have seen elsewhere that are not on the official page
A background only needs to look white; a very light grey or off-white background is treated the same as pure white.
The pages we captured on 2026-09-19 state the colour as an exact value, RGB 255, 255, 255, and state no tolerance band; we did not find one, and we do not know how Amazon's review treats a small deviation. We report your actual pixel values rather than assume a tolerance. Official page: sellercentral.amazon.com
FAQ
What does Amazon mean by a pure white background?
Amazon's main-image requirement pages give an exact colour: RGB 255, 255, 255. The clothing page writes the same colour as hex #FFFFFF or RGB 255-255-255, and the Non-white background page states it inside its suppression trigger. This checker compares the pixels at the four corners and along each edge with that exact value and reports the actual readings.
Is a near-white background, such as a very light grey, acceptable?
Comparing against exactly 255, 255, 255 is our choice, not an Amazon-published threshold: the wording we captured on 2026-09-19 gives the colour as an exact triple, RGB 255, 255, 255, and we found no tolerance band in it, so we compare against exactly that value. We cannot rule out a tolerance stated elsewhere on Amazon's pages, and we do not know how Amazon's review treats a small deviation. We report the RGB value at each corner and, for each edge, the mean and lowest RGB we found, so you can see the size of any difference.
My background is exactly white. Why can the image still be treated as having a non-white background?
Amazon's Non-white background reason lists triggers joined by OR, so either one on its own is enough. One of them is a visual frame, line, or border on any portion of the edges of the image. A thin outline left over from a cut-out, or a faint line added around a white product, meets that description even when every other background pixel is 255, 255, 255. This checker scans each edge for a line that runs continuously along it; because the official wording covers any portion of an edge, a mark on only part of an edge is for you to review.
Are shadows allowed at all?
The phrase 'minimal shadows around the product' appears inside Amazon's trigger wording, not as a permission — the page does not say how much shadow is acceptable. It does state that shadows which run to the edge of the image frame, or that the product or human models cast against a backdrop, are not allowed. This checker looks for a soft, desaturated shadow band running along an image edge — a continuous run of near-grey pixels covering at least a twentieth of that edge. A dark or strongly coloured non-white area at the edge is reported by the pure-white readings instead, and a shadow that stays more than 8 px in from the edge is not judged at all.
Does the white-background rule apply to additional images or only to the main image?
The pages we captured state the pure white requirement for the main image (RGB 255, 255, 255). Amazon's own list of suppression reasons records the scope of each one: on the official list, Non-white background is scoped to main images. The reasons listed against any image are Blurriness or pixelation, Product too small and Prurience. So the pure white requirement and this suppression reason are both main-image rules. We do not state what background additional images may use, because we found no official sentence that says so. The 85% area rule is different: it applies to all product images — the official suppression list scopes Product too small to any image, not just the main image — while the Product image guide words it as 'Show the product as 85% of the image' — the two wordings are set side by side on the product image fill ratio checker.
What happens if Amazon decides a main image has a non-white background?
The official Non-white background page says: "If your images don't comply with our policies, we may: Suppress (hide) your product listing from search until you provide a compliant image". The same page says Amazon may also remove or modify a non-compliant image. This describes Amazon's stated process; it is not a prediction of what will happen to any particular listing.
Can this page make my background white?
No. This page only reads pixels and reports what it finds; it does not modify your file. If a background is near-white rather than exactly white, our flatten background to white tool replaces the near-white background with exact 255, 255, 255 using a deterministic edge fill, and composites transparent PNG areas onto white.
Does this checker also test the 85% product-size rule or the text and logo rules?
No. Those are separate official pages and separate tools. The product image fill ratio checker reports the bounding box around the non-background pixels as a share of the image area — a stand-in that reads higher than the product’s own share when the product is not rectangular — and checks it against the 85% rule. That rule applies to all product images: the official suppression list scopes Product too small to any image, not just the main image, while the Product image guide words it as 'Show the product as 85% of the image', and that page sets the two wordings side by side.
