AI Image Expander
Stretch a photo to a new aspect ratio and let AI outpainting fill the added space.
What expanding is for
Refit a photo to a format
A vertical shot that has to become a 16:9 cover, or a landscape one that has to fit a phone screen. Pick the shape and the sides are painted in rather than cropped off.
Make room for text
Banners and thumbnails need empty space for a headline. Growing the frame gives you that space instead of covering the subject with the title.
Grow one side only
Direction is under Advanced options: add sky above, floor below, or width on the left alone, when only one edge of the composition is too tight.
How to Use AI Image Expander
Upload the photo that is the wrong shape
Drop it above or click to browse. Nothing is watermarked and no account is needed
Choose the shape you need
16:9 for a cover, 9:16 for a phone screen, 1:1 for a feed. Direction and fill are under Advanced options if you want the growth on one side only
Click "Expand"
The AI paints the new area to match what was already there. Download it, or run it again for a different take on the added part
Use this tool via API
Call this tool straight from your own scripts. The endpoint follows the OpenAI REST format and signs requests with a bearer token, so client libraries you already use keep working. You are billed the same token rate as the web app.
