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

1

Upload the photo that is the wrong shape

Drop it above or click to browse. Nothing is watermarked and no account is needed

2

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

3

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

AI Image Expander FAQ

It is the same operation with a different starting point. This page asks what SHAPE you need and works out how much to add — pick 16:9 and a vertical photo grows sideways until it fits. The outpainting page asks how you want the scene continued and leaves the framing alone by default. Use this one when the target format is fixed (a cover, a banner, a phone wallpaper), and that one when you just want more scene.
