The 6 rules Amazon checks before approving your main image
Amazon's image moderation rulebook for the main listing image is short, public, and strict. Most rejection notices reference one of these six rules without telling you which — so sellers end up tweaking everything and re-submitting until something passes. The checker measures all six in one upload.
- 1. Pure white background (RGB 255,255,255) — the background color of the main image must be pure white. Off-white, cream, gradient, or partially transparent backgrounds fail. We measure the four corner regions and compute the mean RGB.
- 2. Product fills ≥ 85% of the longest side — the product's bounding box must occupy at least 85% of the longest dimension. Small products in oversized white frames look unprofessional and convert worse, so Amazon enforces a minimum fill.
- 3. No edge contamination — shadows, gradients, or reflection bleeding into the outermost 5 pixels of any side signal an off-white background to the moderator. We scan every edge and report the percentage of non-white pixels.
- 4. 1000px+ on the long side, square recommended — Amazon requires a minimum of 1000 pixels for the zoom feature to activate. Square 2000×2000 is the modern best practice for high-density screens and zoom UX.
- 5. No added text, badges, or watermarks — the product's own physical label and packaging are fine. Anything added in post (callouts, "Free shipping", brand badges, watermarks) violates the main-image policy.
- 6. Single product, no lifestyle props — the main image is reserved for the product alone. Hands, plants, furniture, food, decor, and other props belong in lifestyle images, not the main shot.
FAQ
Why does Amazon keep rejecting my main image?
Amazon's automated moderator rejects main images for one of six reasons: the background isn't RGB 255,255,255 pure white; the product fills less than 85% of the longest side; there's a gradient or shadow contaminating the edges; text/badges/watermarks have been baked into the image; lifestyle props (hands, plants, furniture) appear; or the file is less than 1000 pixels on the long side. Most rejection notices don't tell you which of these six it was — they just give you a generic 'does not meet image requirements' notice. Our checker runs each rule with specific numbers so you can stop guessing.
What counts as 'pure white' on an Amazon main image?
Amazon's published rule is RGB 255,255,255 — pure white, no tint. In practice their moderator accepts a small tolerance (around RGB 250+) but rejects anything visibly cream, gray, or gradient. We sample the four corners of your image (each 50×50 pixels), compute the mean RGB on each channel, and require all three channels to be ≥ 245 with low variance across corners. A typical 'looks white but actually beige' supplier photo scores 60-80 on our purity scale — flagged as a warning, then fixed by the AI replacement.
What if my product is genuinely small and the 85% rule looks impossible?
If your physical product is small (jewelry, a small electronic accessory, a single capsule), the rule still applies — Amazon wants the product to fill the frame visually, not literally take up the entire physical space. The 85% measurement is on the bounding box, not the silhouette, so a thin product (like a charging cable) can pass by being cropped tighter. The fix repositions and crops the product to ~90% bounding-box fill while keeping aspect ratio safe for Amazon's zoom feature.
Will the fix work if I only have a phone photo and not a studio shot?
Yes — that's the most common input. The fix uses your photo as a reference image and asks the model to keep the exact product identity, proportions, color, packaging, label, and visible materials, then replace only the background with pure white. The output is a safer version of your same photo, not a recreated product. We recommend you visually compare before uploading, since you remain responsible under Amazon's truthful-imagery policy for what's on the listing.
Can the fix handle products with reflective surfaces or transparent packaging?
Reflective products (mirrors, polished metal, glass) and transparent packaging can confuse pure background-removal tools, which is why we use a reference-image fix rather than a cutout. The model keeps the reflection/transparency intact while replacing the surrounding background. Edge contamination (shadows or reflections bleeding into the white) is the most common failure mode here — our edge-shadow scan flags it explicitly so you can decide whether to retake the photo or accept a small remaining shadow.
How long does the full flow take from upload to download?
Compliance check: 2-5 seconds. Free low-res preview generation: 15-30 seconds (rate limited to 5 per hour per IP). HD main image: 30-60 seconds. Full Photo Pack (4 images): up to 90 seconds. The compliance check is free with no signup. You only need to authenticate and spend credits when you want to download the HD version or generate the pack.
