TikTok Shop Product Image Size, Format, Background, and Gallery Roles Explained
When a seller prepares TikTok Shop product listing images, the right file is not just a JPG or PNG. The right file depends on the role: main product image, gallery image, attribute image, description image, size chart image, certification or supporting image, packaging image, or detail close-up.
Official TikTok Shop listing guidance for the US says product images must be at least 600 x 600 pixels, sellers can upload up to 9 square product images, and the first image should show a clear front view. Partner Center upload documentation describes broader image upload constraints and supported formats for API workflows, while Seller Center screens can vary by market and category. Treat official rules as your base, then check the exact current upload screen.
Background and main image expectations
The main image is commonly the strictest image. In US product listing policy, it must use a pure white background and be an objective, straightforward representation of the product for sale. This is different from a lifestyle image. A styled scene may be useful as an additional gallery image, but the first image should make the item easy to identify in a mobile product card.
Role-based image table
| Image role | What it should show | Format/export choice | Main risk | What to preview |
|---|---|---|---|---|
| Main product image | Clear front view of the exact product. | JPG or PNG delivery copy, square, clean background. | Overlay, watermark, nonwhite background, or misleading crop. | First gallery slot and mobile product card. |
| Gallery image | Back, side, close-up, packaging, scale, or use view. | JPG for product photos, PNG for labels or diagrams. | Repeated angle or unsupported claim. | Gallery order and buyer question answered. |
| Attribute image | The selected color, size, style, or variation. | Consistent JPG or PNG matching the variation. | Variant image does not match selected option. | Variation selector and attribute mapping. |
| Description image | Material, feature explanation, measurements, or use instructions. | PNG for text-heavy graphics, JPG for photos. | Tiny text or unsupported sales claim. | Product detail page readability. |
| Size chart image | Measurements for all relevant sizes. | PNG with large text and clean table layout. | Compressed measurements become unreadable. | Mobile size chart display. |
| Certification or support image | Required document or supporting proof when the category needs it. | Use the format requested by Seller Center. | Wrong file role or unreadable document details. | Upload screen and category requirement. |
JPG, PNG, WEBP, HEIC, and heavier formats
For manual Seller Center work, JPG/JPEG and PNG are the most practical product-image delivery formats. Partner Center upload documentation also references additional formats for API workflows, including WEBP, HEIC, and BMP, with conversion behavior in some contexts. Sellers should not assume every format is accepted in every market or every upload surface. If the listing form asks for JPG, JPEG, or PNG, follow that screen.
JPG works well for normal product photography. PNG is safer for text-heavy images, size charts, flat diagrams, transparent graphics, and label close-ups. BMP and other heavy formats can be inefficient even when accepted in a technical upload route, because large files are harder to manage and review.
