Taobao Main Image (≤3MB) preset
800×800 square · JPG · hard ≤3MB limit
Taobao main images must be square, at least 800×800 (zoom requires it) and no larger than 3MB per file. Optimizing quality and size yourself before upload beats letting the platform recompress the original. White backgrounds are a standard requirement to prepare at shooting/design time.

How to use
- Drag your photos into the dashed box above (batch supported — a whole set at once).

- Download individually or as a ZIP after local processing, then upload through the platform as usual.
Platform notes
- Main images below 800×800 break the zoom feature and may block campaign sign-ups.
- The 5th main image often requires a white/transparent background — prepare that at design time, then compress here.
- For detailed HD shots, raise quality to 88–90 while watching the 3MB ceiling.
FAQ
Will files over 3MB be rejected?
Usually yes. 3MB is Taobao’s hard cap for main images; this preset sets the target to 3MB and the predictive engine guarantees you stay under it.
