Amazon product image size and requirements
Amazon accepts a main image at 500×500 or larger, but the number that actually changes your listing is 1000×1000: below it, the zoom feature does not activate. The ceiling is 10000×10000.
Pick the format the platform lists (JPG / PNG), put the product on a pure white background (pure white (RGB 255, 255, 255)), and size the file to the zoom threshold rather than to the minimum. The minimum gets an image accepted; the larger size makes it usable on a phone.
Opens with the Main product image (zoom enabled) preset selected (1000×1000). Drop your images in and export.
The three size thresholds, and which one to target
Amazon is unusual in that it publishes a floor, a useful line, and a ceiling rather than one required size. They answer different questions, so pick the one that matches your goal instead of splitting the difference.
| Spec | Pixels | What it controls |
|---|---|---|
| Smallest accepted | 500×500 | The floor. Anything smaller is rejected at upload. |
| Zoom enabled | 1000×1000 | At or above this, shoppers can zoom into the image on the product page. |
| Largest accepted | 10000×10000 | The ceiling. Nothing larger is accepted, and nothing is gained by going bigger than needed. |
| Minimum width | 1000 px | The width half of the requirement, stated on its own. |
| Background | pure white (RGB 255, 255, 255) | The main image has to sit on white, not on a light gray studio sweep. |
| Formats | JPG / PNG | Upload one of these; anything else fails before review. |
| File size cap | not specified by the platform | Not a fixed byte limit for main images, so keep the file reasonable on your own judgment. |
If you only remember one line from this page: 1000×1000, pure white, JPG. That combination clears the floor with room to spare and turns zoom on.
Why the 500 px minimum is a trap
An image at exactly the minimum is accepted, and that is where the good news ends. A 500 px image on a large product page is upscaled by the browser, and upscaling is what makes a photo look soft, muddy, or artificially sharpened around the edges. Reviewers do not reject it for that, but shoppers scroll past it.
The threshold that matters commercially is the zoom line. Once the image is at or above 1000×1000, the product page offers a magnified view, and shoppers evaluating texture, stitching, or label text can actually see it. Below that line the zoom control is simply absent, and a shopper who wanted a closer look has to leave the page.
Going past the zoom line up to the ceiling of 10000×10000 does nothing for zoom, because zoom is already on. Larger files only cost page weight and your own processing time. A square image at the zoom threshold is the practical sweet spot for most categories.
The pure white background rule
Amazon requires the main image background to be pure white (RGB 255, 255, 255). In practice that means RGB 255, 255, 255 across every pixel that is not the product, with no gray card, no gradient, no soft shadow on the floor, and no off-white paper.
This is the requirement most home-made product photos fail. A photo shot on white paper looks white to your eye, but the camera records it as a slightly warm or slightly gray tone, and a reviewer sees the difference immediately. If your source photo has visible shadow or a gray cast, retouching the tone is not enough; the product has to be cut out and placed on a generated white canvas.
That is also why smoothing shadow edges with a blur does not help. The requirement is not "mostly white", it is white, and a soft gradient into the product silhouette reads as a shadow.
Prepare one main image in five steps
- Start from the largest file you have: Resize down, never up. If the source is smaller than 1000×1000, take a new photo instead of inventing pixels.
- Crop square around the product: Aspect 1:1. Square means no letterboxing later, and no stretched proportions through the middle of the crop.
- Place it on a generated white canvas: Fill the canvas with RGB 255, 255, 255 and composite the product on top. Do not rely on a studio backdrop photo to be white enough.
- Leave a small, even margin: The product should fill most of the frame with breathing room on all four sides. Uneven margins make a grid of thumbnails look crooked.
- Export and check the file: Save as JPG / PNG, confirm the pixel size is at least 1000×1000, and open the exported file once to check the background is white at 100% zoom.
What gets a main image rejected
- Background that reads gray, cream, or blue-tinted next to a neighboring listing in search results.
- Text, logos, watermarks, badges, or borders baked into the main image. Save those for secondary images.
- A product that is cropped by the frame edge, or rotated so that it is not upright.
- Multiple products in one main image, or accessories shown without the main product.
- Upscaled files: size that technically matches 500×500 but with visibly smeared detail.
One master file, several marketplaces
If you sell on more than one marketplace, build the master file at the largest size you need and derive the rest from it. That way the white background and crop decisions are made once, and every derived file inherits them.
The sizes below are the ones most people ask about alongside Amazon. Sort your workflow by size: generate the biggest target first, then step down, so no image is ever upscaled.
| Marketplace | Main image size | Background |
|---|---|---|
| Amazon | 1000×1000 | pure white (RGB 255, 255, 255) |
| Walmart | 2000×2000 | pure white (RGB 255, 255, 255) |
| eBay | 1600×1600 | any background |
| Shopify | 2048×2048 | any background |
| TikTok Shop | 800×800 | pure white (RGB 255, 255, 255) |
Do it in one pass
Select the Amazon rule in the batch image tool, drop the whole product folder in, and it will resize to 1000×1000, pad onto white, and hand back a ZIP. Nothing is uploaded: the work happens in your browser, so a folder of a hundred photos does not need a hundred uploads.
Frequently asked questions
What is the minimum Amazon image size?
500×500. Images below that are rejected at upload. Most sellers should target 1000×1000 instead, because that is where zoom starts working.
Do Amazon images have to be square?
The main image spec on this site is listed as aspect 1:1, and square is what every listing grid expects. A square source at 1000×1000 avoids letterboxing when a marketplace pads it.
Does Amazon limit main image file size?
The spec table records no fixed byte limit for the main image (not specified by the platform). Keep files in the range you would want a shopper to download: a well-compressed square JPG at the zoom size is usually a few hundred kilobytes.
Is a white background required for every image, or only the main one?
The white rule applies to the main image. Secondary images, detail shots, and lifestyle photos can have backgrounds, which is where you show context, scale, and packaging.
Can I resize an existing photo instead of shooting again?
Only downward. Resizing a large photo down to 1000×1000 works well. Starting from something smaller and scaling it up produces a soft result that no amount of sharpening fixes.
