Your product image does not meet TikTok's minimum quality bar. Images must be sharp, well-lit, and at least 800x800 pixels.
TikTok Shop displays products in a video-first feed where image quality dramatically affects click-through. The platform automatically rejects images under 800x800px, JPEG-compressed below visual quality thresholds, or with detected motion blur. Sellers pulling images from older feeds or thumbnail URLs frequently hit this when migrating catalogs.
