Outpaint
AI Extend Image
Outpaint missing edges for wider crops, social formats, or room to place text and product. Works best when the scene has room to continue naturally.

Why AI Extend
When AI outpainting beats a reshoot
AI extend (outpainting) generates new pixels around a photo so the canvas becomes wider or taller while the original content stays as the center reference.
Seamless outpainting
Continues textures, horizons, and rooms so the new edges feel part of the shot.
Format flexibility
Useful when you need more canvas for ads, stories, or print crops.
Center content lock
Keeps the original photo area intact while only inventing the extended borders.
