画像を境界を越えて拡張
任意の写真をズーム アウトして、撮影されなかった部分を AI に埋めさせます。方向と拡張量を選ぶと、gpt-image-1 が元画像の周囲にシームレスで大きなフレームを構築します。
特徴
Programmatic mask, pixel-perfect edges
No painting, no guessing — we compute the exact mask so your original image stays bit-for-bit identical while the AI extends the borders.
All directions supported
Extend up, down, left, right, horizontally, vertically, or symmetrically in all four directions. The tool computes padding and mask geometry for each choice.
Seamless edges
gpt-image-1 regenerates only the transparent border regions while preserving the original pixels exactly. Texture, color palette, and lighting continue naturally.
Flexible scale
+25%, +50%, or +100% — pick the right amount for your composition. Subtle crops benefit from +25%, dramatic expansions go up to +100%.
Pay only for what you use
Each run costs 4 credits (~$0.06) — the same price as a medium-quality edit in the main studio. New accounts get 10 credits on signup so you can try it immediately.
使い方
Three steps to a wider frame
The composer handles the math — you only pick what you want and click.
Upload the image
PNG, JPG, JPEG, or WebP up to 10MB. Works on any aspect ratio.
Pick direction and scale
Choose which side(s) to extend and by how much. The preview shows you exactly where AI will generate new content.
Click Expand Image
gpt-image-1 fills in the new area in about 10–30 seconds. Download the extended image when it's done.
