The Resize feature lets you change the aspect ratio of any image — whether you're converting a portrait shot to a landscape banner or adapting content for different social media platforms. AI automatically fills the expanded areas to seamlessly extend your image. \> **Note:** If you want to change the aspect ratio or extend the canvas of an image, always use **Resize** — not Magic Edit. Magic Edit is designed for modifying existing content within an image, not for changing its dimensions. ### How to Use Resize 1. **Open an image** from your gallery — the image viewer will appear 2. **Click Resize** in the toolbar at the top 3. **Choose an aspect ratio** from the dropdown (top left) or drag the canvas handles to set a custom ratio 4. **Position your image** on the canvas — drag, scale, or rotate it to get the framing you want 5. **Select a resolution**: 1K, 2K, or 4K 6. **Optionally add a prompt** to describe what should appear in the expanded areas 7. **Click Resize** to generate your new image The AI fills any expanded areas naturally, blending seamlessly with your original image. You don't need to add a prompt — but if you want something specific in the new areas, just describe it in the prompt field. ### Available Aspect Ratios Choose from 10 predefined formats:
