What Amazon requires for the main image
Amazon's main-image rules are strict because the main image is what shoppers see in search. This checker looks at the objective, measurable ones:
- Pure white background — RGB 255, 255, 255. This is the rule sellers fail most often.
- Resolution — at least 1,000 px on the longest side for zoom; 1,600 px+ recommended.
- Square aspect ratio — the main image should be 1:1.
- Reasonable file size — large enough to be sharp, small enough to load fast.
Rules that need a human eye — no text or logos, product fills ~85% of the frame, only the product shown — aren't something an automated tool can judge reliably, so check those yourself. The full list is in our Amazon product image requirements checklist.
Guidance, not official validation. This tool gives a fast, heuristic read on the common technical requirements. The background test samples border pixels and can misjudge unusual images, so always confirm by eye. It is independent and not affiliated with Amazon.
Failed a check? Here's how to fix it
- Background not white → use the Amazon white background generator to place your product on pure white.
- Not square / too small → run it through the Amazon image resizer (1,600 × 1,600 px, padded on white).
- File too large → shrink it with the image compressor.
Frequently asked questions
What are Amazon's main image requirements?
A pure-white background (RGB 255), only the product with no text or logos, the product filling ~85% of the frame, a square shape, and at least 1,000 px on the longest side (1,600 px recommended).
How do I check if my image has a pure white background?
Upload it above — the checker samples the border pixels and reports what fraction are white. Well below 100% means the background isn't pure white.
Is this an official Amazon tool?
No. It's an independent, free guidance tool — not affiliated with Amazon and not a substitute for Amazon's own validation.
My image failed the white background check — how do I fix it?
Use the Amazon white background generator to put the product on pure white, then re-run this checker.
