The simple Remove Background node will remove the background from any images fed into it. It will return back the input image in the same aspect ratio or resolution that it was provided in. This is recommended to be used after editing images with transparency originally in them, since most generation and edit models do not support transparency and will add back in neutral pixels instead.
There are no individual models to choose from when using the Remove Background node, so the node is relatively straightforward to configure and use. Simply drag the image input(s) into the node, and then drag the node's outputs to other nodes.
