How it works

Upload Your Image

Choose the photo you want to extend beyond its current borders. Works with any aspect ratio or image size.

Expect: Simple extend: 20-30 seconds. Complex extend: 30-45 seconds and may need refinements.
Describe the Extension

Tell the AI what should appear in the extended areas - new scenery, continued patterns, or creative additions. Specify direction and style to match your vision.

Copy one of these to get started:

extend Extend left and right sides showing more of the street scene with matching urban buildings, parked cars, and sidewalks under the same afternoon lighting
Try This →

extend Extend upward adding more dramatic storm clouds in dark grays and purples matching the moody atmosphere of the original photo
Try This →

extend Extend downward revealing more of the beach with wet sand, small waves, and scattered seashells matching the coastal scene
Try This →

extend Extend all sides to create a wider mountain panorama, adding more peaks, forest slopes, and alpine meadows under the same golden hour light
Try This →

3 more prompts

extend Extend right side showing the continuation of the indoor hallway with matching hardwood floors, white walls, and recessed lighting
Try This →

extend Extend top and bottom creating a taller portrait orientation, adding sky above and ground below while maintaining subject position
Try This →

extend Extend left side revealing more of the formal garden with manicured hedges, stone pathways, and flowering plants matching the estate grounds aesthetic
Try This →
Review Generated Content

Detailed Guides by Scenario

📷

Composition Improvement

Extend image canvas to improve composition — add breathing room, fix tight crops, or reframe for better visual balance.

Common Scenarios

Extending image edges to add negative space around a tightly cropped subject
Widening a portrait from vertical to square format by extending image horizontally
Adding sky or ground to image for a more balanced landscape composition

Best Practices

Describe what should appear in the extended area: 'more sky,' 'continue the grass,' 'extend the wall'
Start with a small extension (20-30%) — too much generates less convincing content
For symmetrical scenes, extending both sides equally gives the most natural result

📷

Platform & Format Adaptation

Extend image to fit different platform aspect ratios without cropping or losing important content.

Common Scenarios

Converting a vertical image to landscape for a website banner by extending the sides
Extending image to fill a 16:9 presentation slide without cropping
Adapting a square image to 9:16 for Instagram stories by extending top and bottom

Best Practices

Specify the target aspect ratio in the prompt — '16:9 for a YouTube thumbnail' is clear
The AI fills extended areas with generated content that matches the existing scene
For banners and headers, extend to leave room for text overlay

📷

Print & Framing

Extend image edges to fit standard print and frame sizes without losing the original subject.

Common Scenarios

Extending image to fit an 8x10 frame from a non-standard phone photo ratio
Adding canvas space to image for a panoramic print or gallery wrap
Extending image borders so the subject isn't cut off at standard print dimensions

Best Practices

Measure the frame or print dimensions first and calculate exactly how much extension you need
For gallery-wrapped canvas, add 1.5 inches of extension on each side for the wrap
Keep the extended content simple — the subject, not the generated background, should be the focus

If something looks off

AI changed the wrong area or something I didn't want changed

Why: The AI couldn't determine exactly which area you meant from description alone.

Try: Tap a marker on the specific area you want to change, then regenerate with the same prompt

Try This →

Tip: Markers tell the AI 'I mean THIS one specifically.' Use them when description alone is ambiguous.

Generated content doesn't match original style

Try:

Describe the visual style explicitly in your prompt (realistic, artistic, photographic). Mention specific elements from the original to maintain consistency.

Try This →

Tip: Try adjusting the prompt if the first result isn't perfect — small wording changes make a big difference.

Outpainted areas look disconnected

Try:

Request seamless blending and describe how elements should flow from original to extended areas. Mention matching lighting, colors, and atmosphere.

Try This →

Tip: Try adjusting your prompt wording if the first result isn't perfect — small changes make a big difference.

Perspective or scale is wrong in extended areas

Try:

Mention perspective alignment in your prompt. For architectural scenes, specify that lines should continue correctly. For outdoor scenes, describe depth and distance.

Try This →

Tip: Mention the desired size relative to other objects, like 'same scale as the other items.'

Extended area is too creative or unrealistic

Try:

Use descriptive language like 'continue exactly as shown', 'match the existing scene', or 'photorealistic extension' to keep generation grounded.

Try This →

Tip: Try adjusting your prompt wording if the first result isn't perfect — small changes make a big difference.

Wrong direction was extended

Try:

Be explicit about direction: 'extend the left side', 'add more sky above', 'show more ground below'. Avoid ambiguous phrasing.

Try This →

Tip: Try adjusting your prompt wording if the first result isn't perfect — small changes make a big difference.

Lighting changes across the extension

Try:

Describe the lighting explicitly: 'maintaining the same afternoon sunlight', 'matching the soft overcast illumination', or 'under identical studio lighting'.

Try This →

Tip: Describe the lighting direction in your prompt, like 'soft light from the left side.'

Quick answers

Do I need to mark where to extend the image?

No marking needed. Just describe which direction to extend (top, bottom, left, right, all sides) and what should appear in the new areas. The AI handles boundary detection and seamless generation automatically.

What's the difference between outpainting and background extension?

Outpainting generates entirely new content beyond borders (revealing more of a scene), while background extension typically continues existing patterns or textures. Outpainting is more creative and can add new elements.

Can outpainting work with any image type?

Yes, works with photos, illustrations, product shots, portraits, and landscapes. Best results come from images with clear context that helps the AI understand what should logically extend beyond the borders.

How do I control what appears in the outpainted areas?

Be specific in your description: mention objects, scenery, lighting conditions, and style. The more detail you provide about what should appear, the better the AI can generate matching content.

Can I outpaint in multiple directions at once?

Yes, you can extend all sides simultaneously or specific combinations (top and bottom, left and right). Describe what should appear in each direction for best results.
