With the rise of generative AI tools in design, Adobe InDesign is now equipped with Generative Expand — a Firefly-powered feature that helps you uncrop or extend image content beyond its original frame. Whether you’re laying out a book cover, adjusting bleed margins, or resizing assets for print and web, this tool can save hours of manual editing.
In this article, you’ll learn what Generative Expand does, how to use it effectively, and when to use it in your design workflow.
What Is Generative Expand in InDesign?
Generative Expand is a generative AI feature inside InDesign that allows you to extend the visible content of an image beyond its edges. It uses Adobe Firefly to intelligently fill in the newly revealed space based on the existing image’s composition, lighting, and context.
Think of it like Photoshop’s Generative Fill, but fully integrated inside InDesign’s layout environment.
What Can You Use It For?
- Extend product shots to fit wider frames
- Create seamless backgrounds for posters or social banners
- Adjust images to fit bleed or trim areas
- Adapt content for different aspect ratios or page layouts
- Fill in awkward white space during layout design
How to Use Generative Expand in InDesign
Here’s a step-by-step guide:
Step 1: Select an Image
- Click on any placed image in your InDesign layout.
Step 2: Increase the Frame Size
- Drag a corner handle outward to expand the frame beyond the original image bounds.
Step 3: Trigger Generative Expand
- Right-click inside the image frame
- Choose Generate > Expand Image
- Or use the contextual Generate button (if visible)
Step 4: Preview & Apply
- Firefly generates a seamless expansion for the added space.
- Review the result and click Apply or Regenerate if needed.
Real-World Examples

Best Practices for Using Generative Expand
- Start with high-resolution images for better expansion fidelity
- Keep prompts simple — Generative Expand auto-generates based on image context (no typing needed)
- Use it on backgrounds, landscapes, and environments for the best results
- Don’t rely on it for perfect symmetry or complex details like logos or faces
Are Generative Expand Results Safe to Use Commercially?
Yes. As with all Firefly features, images expanded with Generative Expand:
- Are safe for commercial use
- Include Content Credentials for transparency
- Are covered under Adobe’s IP indemnity for Firefly-generated content
Export Considerations
Expanded images behave like native assets:
- Can be exported to PDF, EPUB, HTML, IDML
- Work well with bleed and margin settings
- Appear in Publish Online as part of your layout
Summary
Generative Expand in InDesign is a game-changer for designers who need flexible layouts and fast visual iteration. Whether you’re working with bleed margins, resizing for social, or extending a photo to fit a spread — it eliminates the need for back-and-forth with Photoshop.
With just a frame resize and a click, you can turn cropped content into seamless, fully composed visuals.
