Aspect Ratio FAQ
Common questions about ratio changes, cropping, and layout fit.
An aspect ratio describes the relationship between width and height, such as 16:9 or 4:5. It determines the shape of your image and how it fits different screens or layouts. Choosing the right ratio helps prevent unexpected cropping.
Yes, if the target ratio differs from the original, the tool crops the excess area. You can reposition the image within the crop frame to keep the important parts visible. The preview helps you protect key areas before exporting.
