Customizing Image Formats

You can customize the aspect ratio and format by specifying wide, square, portrait, or landscape. You can also define exact aspect ratios like 16:9, 9:16, or 1:2.

Examples

Create an illustration of a sunset over mountains with an aspect ratio of 16:9 using GPT-5 Image.

Editing Images After Generation

You can edit any generated image directly from the image library:

1. Click on an image to open the viewer
2. Click Edit in the bottom bar
3. Paint over the area you want to change using the brush tool
4. Type your edit instruction (e.g. "make it more futuristic", "remove the background")
5. Click Apply

The editor includes an adjustable brush size (10-80px), undo, and clear controls. Editing uses Nano Banana 2 by default and counts as one image credit.
