About Image Expander
A vertical photo that needs to be a website banner: cropping loses the subject, stretching distorts it. Outpainting is the third option — the original stays untouched and the model paints the scene beyond its edges.
Photo editing steps
Prepare your input, choose the edit and review the output before using it:
- Upload an image
- Choose a target ratio
- Position the original
- Outpaint
- Export
How to Use Image Expander
- Upload the image.
- Choose the target ratio.
- Decide where the original sits in the new frame.
- Check the seams in the result.

Image handling and privacy
This is an AI tool: images you upload are sent to the configured inference service for processing, not handled locally in the browser. The active route is managed internally and is separate from the model developer. You can delete any generation from your history at any time.
