3×3图像分割工具

Previously, I used to send a 3×3 grid to Nano Banana Pro and ask it to extract an image by “row and column” — and it failed way too often.

So I ended up building a small tool myself:

Just upload an image ✅
Automatically generate a 3×3 grid ✅
Split it instantly and export any single cell in high resolution ✅。用法：搭配一张参考图，把你的实际产品或人物替换进去，可保持构图不变。
