Overview
This is an official ComfyUI workflow template for removing image backgrounds with BiRefNet, an open model. You load one picture and it returns the subject on a transparent background plus a mask of the subject. It handles fine edges such as hair and fur, and the model file is under half a gigabyte. It suits online sellers, designers and anyone who needs clean cut-outs on their own computer.
It is a small, MIT-licensed model that runs locally, so cut-outs cost nothing per image and your pictures stay on your computer.
Try these first
Start with the first one: it is a small task you can check easily.
- Load a product photo you own, remove the background and zoom in on the edges to check the cut-out.First try · about 0.5 GB download
- Remove the background from this portrait and keep the loose strands of hair.
- Save the mask as well, so I can use it to place the subject on a new background.

How it works
From the creator's documentation.
| Step | What happens | Data goes to |
|---|---|---|
| 1 · Model file | ComfyUI lists the BiRefNet model file to download, about 424 MB | Your computer |
| 2 · Picture | You load one image with any background | Your computer |
| 3 · Cut-out | BiRefNet separates the subject, including fine edges such as hair and fur | Your computer |
| 4 · Results | An image with a transparent background and a mask of the subject | Your computer |
Good to know
Cut the subject out of a photo with the official BiRefNet ComfyUI template. It loads the background-removal model, processes one image and outputs a transparent-background image and a mask.
Limits
- Very cluttered backgrounds, or subjects that blend into the background, can give less accurate masks. The template processes one image at a time and needs a recent ComfyUI version.
