SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the problem of adding believable pixels around an existing image when you need more canvas space, an uncrop, or a new aspect ratio without losing the original subject.

Core Features & Use Cases

  • Smart outpaint routing: Selects the best identity-preserving or reference/brand-matched edit endpoint based on whether your request is prompt-driven, reference-driven, or brand-locked.
  • Aspect ratio changes & uncropping: Expands square/portrait/landscape compositions into wider formats (e.g., 16:9, 9:16) while keeping the visible original content intact.
  • Preservation-focused prompting: Encourages boundary-safe instructions like continuing lighting, camera distance, palette, and central content exactly as in the input.

Quick Start

Ask your AI to outpaint an uploaded photo by extending the canvas to 16:9 while matching the existing lighting, background style, and keeping the original subject and visible area exactly.

FAQPage Schema
How do I extend a photo's canvas to a 16:9 aspect ratio without losing the original subject?

Image outpainting expands the canvas to wider aspect ratios like 16:9 by generating believable pixels around the original content while keeping the visible subject and area exactly intact.

Can I uncrop a portrait image into a wider landscape banner?

Yes, image outpainting performs uncropping by expanding square or portrait compositions into wider landscape formats, preserving the central content and original boundaries during the generation process.

How does outpainting preserve the original image content when extending borders?

Outpainting preserves original content by using boundary-safe instructions that continue existing lighting, camera distance, and palette, routing to identity-preserving edit endpoints to prevent altering the visible input area.

What is the best way to match brand style when generating wider hero image compositions?

For brand style continuation, outpainting routes to reference-matched edit endpoints, using a reference-driven scenario to ensure the extended canvas pixels align seamlessly with your established brand identity.

Does image outpainting work for both prompt-driven and reference-driven scenarios?

Yes, outpainting selects the appropriate edit endpoint based on whether your request is prompt-driven, reference-driven, or brand-locked, ensuring the extended canvas matches your specified style guidance.

When should I use image outpainting instead of standard image generation?

Use image outpainting when you need to change an aspect ratio or uncrop an existing image without losing the original subject, rather than generating a completely new image from scratch.
