Image Expand Node

The Image Expand node extends your images beyond their original boundaries using AI-powered outpainting. You control exactly how much to expand on each side and can optionally provide a prompt to guide the generated content.

What It Does

Outpainting is the process of generating new visual content outside the existing borders of an image. This node lets you add pixels to any combination of edges -- top, bottom, left, right -- or apply a uniform zoom-out effect. The AI analyzes the existing image and produces seamless extensions that match the original style, lighting, and perspective.

Configuration

Parameter	Description	Range
Expand Top	Number of pixels to add above the image	0 -- 700 px
Expand Bottom	Number of pixels to add below the image	0 -- 700 px
Expand Left	Number of pixels to add to the left of the image	0 -- 700 px
Expand Right	Number of pixels to add to the right of the image	0 -- 700 px
Zoom Out	Uniform expansion percentage applied to all sides	0 -- 90%
Prompt	Optional text guidance describing what the expanded area should contain	Free-form text

Usage

1. Drag an Image Expand node onto the canvas.
2. Connect the output of an Image Generator, Asset Node, or any other image-producing node to its input.
3. Set per-side pixel values or use the Zoom Out slider for uniform expansion.
4. Optionally write a Prompt to guide the AI on what content to generate in the expanded area (for example, "continue the forest landscape with a river").
5. Execute the node to produce the expanded image.

tip

When changing an image's aspect ratio for a different platform (for example, converting a 1:1 image to 16:9), use the left and right expand values to add horizontal content while leaving top and bottom at 0.
