How to extend an image for a wider or square layout

Before you start

Start with a source whose important subject is intact. Decide the target layout before generating, leaving space where a headline or interface might sit. Avoid expecting the tool to reconstruct a missing logo, hand, or product component accurately from a cropped fragment.

Step by step

1. Upload the source

   Open the image extender and upload the photograph. Keep the original file so you can check the subject after the edit.

2. Choose the target shape

   Use Square, Tall, or Wide below the presets to choose the target shape. Customize contains the full list of supported aspect ratios. Choose Custom if you want to describe how the new area should look.

3. Keep the direction simple

   Ask for more of the existing background with consistent perspective and lighting. If you need empty space for text, say where it should go rather than asking the model to write the headline into the image.

4. Generate and inspect the join

   Review the estimate before generating. Compare the result with the source, especially along the boundary where the original scene meets the newly generated area.

What to check in the result

Follow straight lines such as shelves, table edges, tiles, and horizons across the extended area. Repeated patterns, bent geometry, and extra objects often reveal an otherwise convincing edit. Check that the model did not enlarge or move the subject when it added the surrounding space.

If the result needs another attempt

If the new area looks busy, ask for a simpler continuation with no additional objects. Try a smaller change of aspect ratio when the requested canvas would require inventing most of the scene. Use upscaling when the framing is already right and you only need more pixels; extension solves a different problem.
