What the border estimate measures
The checker samples pixels around the image border and corners, allowing a small tolerance for neutral near-white compression variation. Appears white means most sampled pixels pass; Mostly white is a mixed border; Not predominantly white means too few sampled pixels are near white.
- It is a pixel estimate, not an AI segmentation model.
- The source is analyzed locally.
Important visual limitations
Shadows, reflective objects, white products, textured backgrounds, and products touching the edge can distort border sampling. The result does not inspect the full scene and cannot guarantee Amazon approval.
- Inspect the full image at normal size.
- Use the Amazon tool for separate sizing and framing checks.
Questions, answered.
What does Appears white mean?
At least about 90% of sampled border pixels matched the near-white tolerance.
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. Amazon content and category rules require human review.
