What Amazon checks on the main image
Amazon's main image rules are non-negotiable: a pure white background (RGB 255,255,255), the product filling at least 85% of the frame, a minimum of 1000px on the longest side, no text, logos, watermarks, or props, and a JPEG, PNG, or TIFF file.
Why checking before upload matters
When you upload through Seller Central, the submission itself triggers Amazon's review — there is no preview. If the image fails, your listing can be suppressed and drop out of search.
