TikTok Shop: Image too small
Image dimensions below 600×600What's happening
TikTok Shop has a universal hard floor of 600×600 px, images below this are rejected outright. The "Good" listing tier requires ≥5 images of high resolution (800×800+ recommended); the tier model is about image count and quality, not separate pixel thresholds per tier. Below the 600×600 floor, your listing can't qualify for any tier.

Replace source images with higher-resolution versions (≥800×800 recommended), re-export, re-upload, wait for TikTok to re-validate.
Fix it with Emberfeed
Emberfeed cannot fix this one. Its served feed goes to a TikTok Ads catalog, not to your Shop listing, and a render cannot add detail a small photo does not have: rendering a 400 px photo at 1024×1024 only enlarges its pixels. The fix is larger source photos. Once your store serves them, Emberfeed picks up the new image URLs on the next hourly refresh.

Catch TikTok feed issues before they do.
Emberfeed checks every product against TikTok's required fields and format rules, and most problems come with a fix: a field rule for the whole feed or an override for one product.
Emberfeed is a hosted tool: it imports your existing product feed, renders every product image through one template and serves a new feed URL for Meta, Google, TikTok, Heureka, Zboží.cz and Glami. It costs 25 € per feed per month, and the first 3 months are free on one feed up to 1,000 products.
