AI 画像エクスパンダー: 任意の写真を無料で境界を超えて拡張

I create LinkedIn banner images for professionals. MyShell's image expander lets me take any portrait photo and widen it to 1584×396 LinkedIn banner format in under 60 seconds. The outpainting fills in background seamlessly — no seam at the expansion boundary. Free vs Canva Pro $13/month.

E-commerce photographer here. Half my product shots have too-tight crops for Amazon hero images (which need extra whitespace on all sides). MyShell expands 1:1 squares to 16:9 in under 60 seconds with realistic product reflections and background continuation.

Travel blogger. I often shoot vertical 9:16 on my phone and need 16:9 for YouTube thumbnails. MyShell's image expander adds correct landscape continuation to the sides — sky matches, horizon line extends, foreground texture matches. No visible seam. Takes about 45 seconds.

Social media manager at a small agency. MyShell image expander creates story (9:16) and feed (1:1) versions from a single 16:9 client photo by extending top/bottom. Saves about $40/month in Firefly credits for background generation. Clients can't tell the difference.
