Image expansion on Caimera uses AI to extend the borders of an image—adding new visual content that blends naturally with the original. This is especially useful when:

• You need to fit a specific aspect ratio
• You want to add breathing room around a subject
• You’re repurposing an image for banners, thumbnails, or product modules

This article will guide you through the process of expanding an image.

🛠️ Step-by-Step: How to Expand an AI-Generated Image

Step 1: Generate Your Base Image

Start with an image that’s close to your target dimensions. For example:

This minimizes how much expansion is needed later.

Step 2: Navigate and Click on the Expand tool.

Step 3: Increase the size of the image you want to expand by in pixels on the sides you want to expand it on. The maximum limit is 200 pixels.

• Total vertical expansion needed: 300 − 242 = 58 px
• Since the width is already correct (970 px), you don’t need to pad on the left or right sides. You’ll want to split the vertical padding evenly:

Top: Add 29 px

Bottom: Add 29 px

Left: 0 px

Right: 0 px

Step 4: The expanded image is now available under the 'Layers' on the right side.

Step 5: Upscale the image for high resolution output. Click 'Apply'.
