2026 Amazon Image Requirements Checklist
Amazon main images are judged more strictly than secondary listing photos. Treat the first image as a clean catalog asset: the product is the hero, the canvas is white, and anything that looks like advertising or decoration is a risk.
Use at least 500px on the longest side, with 1000px+ preferred for zoom-friendly detail views.
Main images should sit on a pure white background, commonly expressed as RGB 255,255,255.
Remove promotional text, badges, logos, borders, watermarks, inset images, and decorative overlays.
Pass before upload
- Product is sharp, centered, and easy to recognize.
- White background reaches the canvas edges.
- Image is large enough for quality inspection.
- Nothing in the image looks like a promotion.
Fail or revise
- Text, arrows, star ratings, or badges appear on the main image.
- Background is gray, transparent-looking, patterned, or lifestyle-based.
- Product is too small, cropped, blurry, or partly hidden.
- Props or accessories could mislead the buyer.
Main image vs additional image checks
Main photos are stricter; secondary photos can explain context, scale, and use cases.
The main image mode in this tool is intentionally stricter. It treats non-square canvases and non-white edge samples as upload risks, and it reminds sellers to manually inspect text, badges, borders, watermarks, and framing.
Additional image mode is more flexible because secondary photos can explain scale, use cases, compatibility, packaging, installation, and product details. They still need quality control: keep claims accurate, mobile-readable, and useful to shoppers.
Why images affect conversion rates
Image quality affects trust, click-through, zoom interaction, and perceived product value.
Amazon shoppers often compare products from search results before reading long descriptions. A small, off-ratio, heavy, or inconsistent product photo can make a listing feel less reliable even when the product itself is competitive.
This free Amazon image size checker helps sellers catch common problems before upload. It is not a replacement for official marketplace policy, but it gives operators a fast pre-flight check for dimensions, ratio, file size, and practical repair steps.
Amazon image size FAQ
What Amazon image size should I use?
Use a square, sharp source image whenever possible.
A 1000x1000 pixel image is a useful baseline for many listings because it is square and meets the long-side threshold used by this checker for zoom eligibility.
Are main and additional image requirements the same?
No. Main images are the strictest listing asset.
Main images are stricter because they are the primary marketplace representation of the product. Additional images can show lifestyle context, details, scale, compatibility, and explanatory graphics.
Can this tool fix a non-square product photo?
Yes, it can export a white 1000x1000 JPG canvas.
After Turnstile verification, the browser can generate a 1000x1000 JPG with a pure white canvas and draw your original image proportionally in the center without stretching the product.
Is my product image sent to a server?
No. Validation runs locally in your browser.
The validation and canvas export happen locally in your browser. The only network request in the protected download flow is a Turnstile token verification request to the configured Cloudflare Worker endpoint.
