# Bria Eraser, Expand Image, and GenFill in ComfyUI

> Remove objects, expand images, and generate content inside masked regions with the Bria Eraser, Expand Image, and Generative Fill partner nodes in ComfyUI.

Bria's image editing tools are available in ComfyUI as Partner Nodes. This page covers three mask-based editing workflows: **Bria Eraser** (remove objects), **Bria Expand Image** (outpaint beyond the borders), and **Bria Generative Fill** (generate content inside a masked region). All three keep everything outside the edited area pixel-perfect unchanged.

## What Bria Image Editing is good at

* **Object removal**: Bria Eraser erases a masked object or region and fills it with surrounding context, no prompt needed
* **Image expansion**: Bria Expand Image outpaints beyond the original borders, generating surroundings that match the image's lighting, perspective, and texture
* **Generative fill**: Bria Generative Fill regenerates a masked region from a prompt, art-directing new content into the scene
* **Pixel-perfect preservation**: All three workflows keep everything outside the edited area unchanged
