Resize & Fill

Expand or crop an existing image to fit a new size or aspect ratio. When the canvas is extended, the system generates new content that blends seamlessly with the original image.

This capability can be used across Text-to-Image outputs, Scene Forge scenes, and Reimagine edits when adapting creatives to different formats.

How It Works​

AI expands or crops an existing image to fit a new size or aspect ratio. When the canvas is extended, the system generates new content that blends seamlessly with the original image.

How to Use​

Step 1 — Open Resize & Fill​

From an existing image variation, click the edit action to open the Resize & Fill dialog.

Step 2 — Adjust the Canvas​

Use the canvas handles to control the new dimensions.

  • Drag outward to extend the image (AI fills the new area).
  • Drag inward to crop the image.

Step 3 — Describe the Fill (Optional)​

Add a prompt describing what should appear in the extended area.

Example: "white studio background with soft shadow"

If left empty, AI automatically analyzes the image and fills the space.

Step 4 — Apply​

Click Apply Changes to generate the resized image. Generation takes 1–2 minutes and produces a new variation.

Options​

  • Prompt: Optional description of the fill content.
  • Output Dimensions: Set by dragging canvas handles (max 4096 px per side).
  • Canvas Adjustment: Crop or extend any edge (left, right, top, bottom).

Best Practices​

  • Leave the prompt blank for simple or studio-style backgrounds.
  • Avoid extreme aspect ratio changes in one step.
