You have finished the product shoot, edited the photos and uploaded your listing, only to see a red flag in Seller Central or your image quietly suppressed a week later. Image rejections are one of the most frustrating parts of selling online, partly because different marketplaces reject for different reasons, and partly because the rejection message rarely tells you what actually went wrong.
This guide breaks down why product images get rejected on the major marketplaces in 2026, what each platform actually checks, and how to fix the most common problems before they cost you a live listing.
Why rejections matter more than they used to
Marketplaces have moved from manual review to automated image checks. Algorithms now sample your image the moment you upload it, and many run background checks retroactively on listings that are already live. On Amazon and Walmart, an image that fails the check is not just refused at upload; a previously accepted image can be suppressed later, which pulls your main photo and can hide the entire listing from search.
The practical effect is that a single non-compliant image can take a selling product offline overnight. Getting your images right the first time is far cheaper than chasing reinstatements.
The most common rejection reasons
1. The background is not pure white (when it needs to be)
This is the single biggest cause of rejection on marketplaces that mandate a white main image. Amazon and Walmart both require a genuinely pure white background, meaning sRGB values of exactly 255, 255, 255. Their algorithms sample the corner pixels of your main image and expect them to read as pure white.
The trap is that "looks white" is not the same as "is white". A soft grey gradient from a lightbox, a faint blue cast from daylight, or a drop shadow that bleeds to the edge of the frame will all fail the check even though the background looks white to your eye. Around nine out of ten Amazon rejections come down to background.
The fix: Do not rely on your camera or a lightbox to produce a perfect 255 white. Shoot on a clean, evenly lit background, then clean the background in editing so the corners read as true white. Check the actual pixel values with the colour picker in your editor rather than trusting your eye.
2. Watermarks, logos, text and badges on the main image
Photographer watermarks, brand badges, "Best Seller" flashes, size labels and promotional text such as "Free Shipping" are prohibited on the main image across almost every major platform. eBay goes further and bans watermarks, text overlays, logos and URLs on any listing image, not just the main one, and will remove listings that break the rule.
The fix: Keep your main image clean and product-only. If you want to add callouts, dimensions or feature labels, put them on your secondary or gallery images, where marketplaces that allow infographics (such as Shopee and Lazada) let you use them.
3. The image is below the minimum resolution
Every marketplace has a floor, and uploading below it is an instant rejection. Just as damaging, uploading only just above the floor disables zoom, which hurts conversion even when the image is technically accepted. Amazon needs at least 1,000 pixels on the longest side to enable zoom, and recommends 2,000 to 3,000 pixels. Walmart automatically unpublishes any primary image below 500 x 500 pixels.
The fix: Shoot and export large. A 2,000 to 3,000 pixel square is comfortably above every marketplace floor and enables zoom everywhere, so you can produce one high-resolution master and resize down per channel.
4. The product is too small in the frame
Marketplaces expect the product to dominate the image. Amazon requires the product to fill at least 85% of the frame, Lazada recommends at least 80%, and Shopee at least 70%. Too much empty space around the product is a quiet quality-score killer even when it does not trigger an outright rejection.
The fix: Crop so the product fills the recommended proportion, but leave a small even margin so nothing touches the edges. Do not crop so tightly that the product is clipped, which is itself a rejection reason.
5. File format or file size problems
Marketplaces accept a limited set of formats and enforce maximum file sizes. Etsy limits each file to 1MB, Shopee to 2MB, Lazada to 3MB and Walmart to 5MB. An oversized file is refused at upload; the wrong format (for example a GIF where only JPEG and PNG are allowed) is equally rejected.
The fix: Export as JPEG for opaque product photos and compress to sit comfortably under the platform's limit without visibly degrading quality. This is exactly the kind of repetitive resize-and-compress job that a tool like PixelPrep is built for, letting you produce marketplace-ready files at the correct dimensions and file size in one pass.
6. Prohibited or "disturbing" content
Some rejections are about what the image shows rather than its technical specs. Amazon prohibits showing accessories or props that are not included in the purchase on the main image. Shopee bans images that can cause discomfort or disgust, which catches treatment products such as scar or burn creams that display an actual affected area; use an illustration or icon instead. Intellectual-property issues, such as another brand's logo appearing in your shot, will also get a listing pulled.
The fix: Show only what the customer receives, avoid graphic close-ups on health and beauty products, and make sure no third-party branding is visible in the frame.
Marketplace image rules at a glance
Because the thresholds differ, it helps to see them side by side. The figures below are the 2026 specifications for the main product image.
| Marketplace | Minimum size | Recommended | Max file size | Pure white main? | Watermarks/text? |
|---|---|---|---|---|---|
| Amazon | 1,000 px longest side | 2,000 to 3,000 px | Large (multi-MB) | Yes (RGB 255,255,255) | Not allowed on main |
| Walmart | 500 x 500 px (auto-unpublish below) | 2,200 x 2,200 px | 5MB | Yes (RGB 255,255,255) | Not allowed on main |
| eBay | 500 px longest side | 1,600 px or more | Generous | Not required | Banned on all images |
| Shopee | 500 x 500 px | Higher for zoom | 2MB | Recommended, not required | Allowed on gallery |
| Lazada | 330 x 330 px | Up to 2,000 x 2,000 px | 3MB | Recommended, not required | Allowed on gallery |
| Etsy | 2,000 px recommended | 2,000 px or more | 1MB per file | Not required | Allowed (your choice) |
How to stop rejections before they happen
Most rejections are predictable, which means most are preventable with a consistent pre-upload routine. Run through this checklist before every listing goes live:
- Check the corners are true white. Use your editor's colour picker on the four corners of any main image bound for Amazon or Walmart and confirm they read 255, 255, 255.
- Strip the main image clean. No watermarks, logos, promotional text, badges or props that are not included in the sale.
- Start from a large master. Keep a 2,000 to 3,000 pixel square original so you can resize down for every channel without ever falling below a floor.
- Match the frame-fill rule. A product filling 80 to 85% of the frame satisfies nearly every marketplace at once.
- Confirm format and file size per platform. JPEG for photos, and compress under the tightest limit you are targeting (1MB if you sell on Etsy).
- Review category-specific bans. Health, beauty and anything showing a treated area needs extra care on Shopee.
If you sell across several channels, the real time sink is producing the right dimensions and file sizes for each one from a single set of photos. Automating that resize-and-compress step, rather than exporting each variant by hand, is the difference between a five-minute upload and an afternoon lost to rejected images.
The takeaway
Image rejections almost always trace back to the same handful of causes: a background that is not truly white, a watermark or text on the main image, a file that is too small or too large, or a product that does not fill enough of the frame. None of these are hard to fix once you know the exact threshold each marketplace enforces. Build a clean, high-resolution master image, check the white point and the frame fill, and resize to each channel's specification before you upload. Do that consistently and rejections stop being a recurring emergency and become a problem you have already solved.
