Most listings that get suppressed for images fail on one of three things: the background is not quite white, the product is too small in the frame, or there is something in the main image that is not the product. None of those need a photographer to fix. All three are worth understanding precisely, because the first check is automated and it does not negotiate.
A note before the numbers. Amazon's own image guidance lives inside Seller Central, behind a login, and the public guides that rank for this query disagree with each other on several figures. Where that is the case below, I have said so rather than picking the confident-sounding number. Check the current style guide for your category before you re-shoot anything expensive.
The main image rules
The main image, the one that shows in search results, is the strictest. It has to be:
- On a pure white background, RGB 255, 255, 255. This is the one that bites. Off-white is not a matter of taste here. Sellers report near-white values like 252, 252, 252 being flagged, because a machine is sampling pixels rather than forming an opinion. A photo shot on a white sheet in daylight is almost never 255 white, it is a very light grey with a colour cast.
- At least 85% filled by the product. Jewellery and watches are commonly cited as an exception at 75%, but category style guides vary, so treat 85% as the working figure unless yours says otherwise.
- The actual product, by itself. No props, no text overlay, no watermark, no logo, no borders, no lifestyle setting, no placeholder or illustration. Text that is physically printed on the product or its packaging is generally fine, since that is the product.
- Not a drawing or a render presented as a photo, for most categories.
The other images in the gallery are much looser. That is where lifestyle shots, scale references, detail crops and infographic-style overlays belong, and where most of the selling actually happens.
The numbers
| Thing | Figure | How settled is it |
|---|---|---|
| Longest side, for zoom | 1,000 px | Amazon staff forum posts state this |
| Longest side, recommended | 1,600 px or more | Stated as the optimal target |
| Maximum dimension | 10,000 px | Stated by Amazon staff |
| Absolute minimum accepted | 500 px | Third-party guides only, and disputed |
| Formats | JPEG, TIFF, PNG, non-animated GIF | JPEG preferred |
| Colour mode | sRGB or CMYK | sRGB is the safe answer |
Zoom is the figure worth caring about. Below 1,000 px on the longest side the listing loses the hover-to-zoom behaviour, and zoom is one of the few image properties with a visible effect on conversion, because it is how a shopper checks a material or a seam before buying. Shooting for 2,000 px square costs nothing extra and clears every threshold with room spare.
Guides that confidently assert a single minimum are usually quoting each other. The 500 px figure in particular comes up repeatedly in third-party posts and not in anything traceable to Amazon.
Why "white background" is harder than it sounds
Put a product on a white sheet, shoot it, and open the file in any editor with an eyedropper. The background will read somewhere around 230 to 245, with a tint: cool and blue near a window, warm and yellow under a room light. The eye corrects for this automatically and the sampling check does not.
The three common fixes, in order of how well they hold up:
- Cut the product out and composite it onto pure white. This is what a compliant image actually is. It survives any check because the background is literally 255, 255, 255, not a photograph of something white.
- Shoot in a lightbox and correct the white point. Workable, slower, and you still have to verify the result pixel by pixel.
- Raise the exposure until the background clips to white. This is the one that quietly ruins listings. Pushing exposure far enough to clip the background also blows out the product's own highlights, so a white trainer loses its stitching and a glass bottle loses its edge. The image passes the background check and stops showing the product properly.
Option three is worth naming because it is the default thing an exposure slider does, and it is why a lot of technically compliant Amazon images look flat.
A pre-upload checklist
Before anything goes to Seller Central:
- Eyedropper four corners of the main image. All four read 255, 255, 255.
- The product's bounding box covers at least 85% of the frame, with a small consistent margin rather than a tight crop.
- Longest side is 1,600 px or more, and square unless the category says otherwise.
- No shadow that runs off the edge of the frame. A contact shadow under the product is fine, a cast shadow hitting the border reads as background content.
- Nothing in the frame that is not the product: no hands, no stands, no size cards, no reflections of the room in a glossy surface.
- sRGB, saved as JPEG at high quality rather than maximum compression.
Doing this at volume
The rules are per-image, which is the real problem. A twelve-product catalogue needs twelve compliant main images plus a gallery for each, and the work does not get faster with practice because it is mechanical rather than skilled.
That is the part Instant Studio handles: one phone photo of the product goes in, and a set of shots comes back cut out, composited on true white, framed to the fill requirement and exported at marketplace dimensions. The compliance arithmetic above is applied for you, so the decision left to make is which shot sells the thing best, not whether the background is 253 or 255.
