Extend an image
Grow an image beyond its original borders and let the AI paint the new area — outward-only outpainting, launched from the same button as Crop.
Extending (also called outpainting) grows an image outward past its edges and asks the AI to fill the new space with a natural continuation of the scene. It’s the mirror image of cropping: crop trims inward, extend adds outward. Your original stays put — the extended picture arrives as a new layer.
When to use
- A render is framed too tightly and you want more room — sky above a building, foreground in front of it, or width for a banner.
- You need the same image at a different aspect ratio without squashing it — extend to 16:9 for a slide, 9:16 for a phone, and so on.
- You like the composition but want to reveal more of the world around it.
Steps
- Select the image layer you want to extend.
- Open the Crop tool — the Crop button in the layer’s floating action row.
- In the toolbar, switch the Crop ⇄ Extend toggle to Extend.
- Add space: drag any edge or corner outward to pad that side, or pick an aspect-ratio preset — Free, 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3 — to grow the frame to that shape, centered on your image.
- Press Generate on the prompt bar (or Enter) to render. There’s no “Done” button — extending is a generation. Press Esc or the ✕ to cancel without rendering.
How it works
- Extend is outward-only — the box can never move inside the image (to trim inward, use Crop instead).
- The original pixels are preserved at their size; only the added border is newly generated, so the AI blends the extension into what’s already there.
- No prompt needed — the AI reads the existing image and paints a matching continuation. Just extend and Generate.
- It uses the model you’ve picked in the model picker and costs credits like any render, deducted only after it succeeds. The result is a new layer.
Tips
- Extend in modest steps. A very large extension in one pass can look invented, or be rejected as too extreme for the model — grow a bit, generate, then extend again for big expansions.
- With some models you must choose an aspect-ratio preset (the Free option is disabled) — pick the ratio closest to what you want.
- Combine with Crop: reframe tight first, then extend the side you actually want more of.
