Questions
Is the result a guarantee?
No. It measures the rules that can be measured from pixels. Marketplace review can still reject a photo for content, such as props or text, and rules differ by category.
Why did a white product fail or show “check by eye”?
A white product on a white background has almost no edge to measure. The tool tells you so instead of guessing.
Do you keep my photo?
No. The photo is read by your browser and never leaves your device.
