Why use Backgroundcanvas AI outpainting
Seamless edge blending
AI continues backgrounds, skies, and textures so new pixels blend naturally with your original image.
Keep the original intact
Your source photo stays locked in the center. Only the outer expansion regions are generated.
Optional prompt control
Describe what to generate in expanded areas — e.g. "continue the forest" or "extend the city skyline".
