Frequently Asked Questions

Is my photo uploaded? +

No. Segmentation, blur, composition, and export run inside your browser.

What creates the best result? +

Use a sharp subject with visible contrast from the background and avoid heavy motion blur.

What does edge feathering do? +

It softens the transition around the detected subject to make the composite feel more natural.

Why is the first run slower? +

The browser downloads and caches the reusable segmentation model on first use.
