Start with the technical floor
Current TikTok Shop US seller guidance requires product images at least 600 × 600 pixels and supports JPG/JPEG/PNG listing imagery. The add-product guidance states a maximum of 10 MB per image and up to nine product images.
Treat the main image differently
TikTok Shop policy describes the main image as a front physical view of the product and requires a pure white background. Added logos, text, borders, watermarks, promotional graphics, or misleading visual treatment can create listing problems.
Use the remaining images to answer buyer questions
Additional images should show different angles, details, included accessories, variation context, and useful scale rather than repeating the same view.
Why technical checks are only a preflight
A local checker can measure dimensions, file size, format, square framing, and approximate border whiteness. It cannot judge whether the physical product matches the listing or whether content violates category or intellectual-property rules.
Official marketplace references
Requirements can change. Review the source before publishing an important listing.
