Extend a Scene Beyond Its Current Frame
An image extender creates new surroundings outside the original edges. Choose an available target ratio and review how horizon, perspective and texture continue. The additional scenery is generated, not recovered from a hidden wider version of the photograph.

Give a Portrait Room to Breathe
A tightly framed subject can leave little room for a layout. Expand the surrounding scene to explore a different composition without simply enlarging the whole picture. Inspect the boundary where the original meets the generated area, especially around complex backgrounds.
Expand Your Image
Make Space for a Headline
A wider backdrop gives text room without covering the main subject. Generate the extra space first, then add copy in your editor. Keep original product details as the reference and inspect expanded surfaces for repeated patterns or inconsistent shadows.

Adapt a Photo to Another Format
Explore a banner, social post or portrait composition using the ratios in the tool. Expansion differs from stretching and resolution upscaling. Select the shape you need, then compare the result with the original before exporting into your final layout.

Fit a Different Post Format
Choose a supported ratio and inspect the generated surroundings. Add platform-specific text and safe margins during final design.
Explore a Wider Composition
Use the expansion as a creative edit while keeping the untouched photograph. Generated edges should not be treated as documentary detail.
Leave Room for a Headline
Create space around a subject and add editable text afterward. Review the full output at its intended display size.
Improve a Layout Starting Point
Prepare a flexible frame instead of stretching the image. Check perspective and repeated texture at the extension boundary.

AI Image Extender: Common Questions
What does AI Image Extender do?
Expand an image beyond its original edges with Seedance's AI image extender. Choose a new aspect ratio and generate additional surroundings for banners, vertical posts and wider compositions.
Does uncropping recover the original photo outside the frame?
No. The new area is generated from the visible image. It is a plausible extension, not a recovery of content that was cropped away.
How is an image extender different from an upscaler?
An extender adds visual content around the frame. An upscaler increases pixel dimensions or apparent detail. Choose a different aspect ratio here when you need more space around your subject.
How do I get started?
