Does my photo get uploaded to a server?

No — the segmentation model (4.4 MB) downloads to your browser once and every photo is processed on your device. That's the whole point of this tool.

What backgrounds can I put behind the cutout?

Nothing (transparent PNG), a solid color, a two-color gradient, another photo, or a blurred version of the original — and switching styles never re-runs the AI.

What does it work best on?

Photos with a clear subject: people, products, pets. Fine hair and glass edges are genuinely hard; the edge-softness and defringe controls help.
