Channel requirements
TikTok Shop main image requirements
Curvi builds TikTok Shop main images to the rules below, then measures the output pixels against the size, background and fill rules before a file ships. This spec is compiled from public guidance and is pending verification against official documentation.
| Rule | Requirement |
|---|---|
| Recommended size | 1200 by 1200 px |
| Background | White preferred |
| Text on the image | Not allowed |
| Formats | jpg, png |
| Maximum file size | 5 MB |
| Maximum image count | 9 |
What this means in practice
A white background is preferred. It is not a hard rejection rule, but white mains convert better and avoid manual review.
No text, watermarks or badges on this image. Promotional text belongs in secondary images or ad creative, never on the TikTok Shop main image.
Built to this spec from one photo
Curvi builds TikTok Shop main images from one photo of your product, measures the output pixels and attaches the report. A file that still fails a check after a retry is marked for review, and you are not charged for it.
