Remove Background

Cut the subject out of any photo into a transparent PNG — hair and fine edges included.

WHEN TO USE
Isolate a character, product, or prop so you can composite it onto a new background or reuse it as a reference.
PAIRS WELL WITH
Canvas image nodes (use the cutout as a reference), Restyle Background, Layout.
💡 For people, try Portrait mode first — switch to Hair & Fur only when stray hair strands matter.

Remove Background cuts the subject out of any photo and returns a transparent PNG — hair, fine edges, and semi-transparent detail included. Results are also saved to your Workspace, so you can reuse the cutout in the Canvas or Studio.
