When using a preset template, your uploaded original image will be centered on the new canvas by default, and AI will expand evenly outwards. If you want more flexibility in controlling the canvas size, you can choose a custom size. The original image will then be fixed in the top left corner of the canvas, and AI will fill the expanded area from that position to the bottom right. This method is particularly suitable for situations where you need white space on the right or bottom of the image to add text descriptions, brand logos, or other design elements.
