How to expand images with AI outpainting

No software install — extend photos in your browser. Pick a target ratio and output size, then let AI fill the new canvas seamlessly.

  1. 1. Upload your image

    Click "Upload image", drag a file into the area above, or paste with Ctrl + V. Supports JPG, PNG, WebP, AVIF up to 10MB.

  2. 2. Choose ratio and output size

    On the editor page, select a target aspect ratio (1:1, 16:9, 9:16, etc.) and canvas dimensions. Preview shows where AI will expand.

  3. 3. AI expands the canvas

    AI outpainting continues the scene beyond the original frame — matching lighting, perspective, and texture at the edges.

  4. 4. Compare and download

    Review before/after with the compare slider, then download the full-resolution expanded image.
