Check whether a product-photo border appears white

The checker samples pixels around the border and corners and allows a small tolerance for neutral near-white compression variation. It reports how much of that sampled edge looks white so you can catch off-white sweeps, gray corners, or edge shadows before marketplace review.

  • Appears white means most sampled edge pixels pass the near-white tolerance.
  • Mostly white means the border is mixed.
  • Not predominantly white means too few sampled edge pixels are near white.

Use the result as a screening signal, not a compliance verdict

A white subject touching the edge, reflective products, shadows, textured backgrounds, or a white frame around a non-white center can confuse border sampling. The checker is not segmentation, background removal, or a guarantee of Amazon or marketplace approval.

  • Inspect the full image at normal size.
  • Use Amazon Image Resizer for separate dimension and framing checks.
  • Review current marketplace content rules before publishing.
Frequently asked

Questions, answered.

How can I check if an image background is pure white?

Use the border estimate as a quick screen, then inspect the complete image. Pure white pixels are RGB 255,255,255, but an automated border sample cannot validate every interior pixel.

Why can a white product confuse the result?

Border sampling cannot reliably separate a white subject touching the edge from its background.

Is this an AI background remover?

No. It neither segments nor alters the subject.

Does it guarantee Amazon approval?

No. Marketplace content and category rules still require human review.
