Tips for this size
A 16:9 image shows uncropped in the timeline.
Upload at the exact size where you can, because platforms recompress images and resizing twice softens them. If your image has a different shape, it will be cropped or padded. The Image Resizer lets you choose, and everything runs in your browser. Work out other dimensions with the Aspect Ratio Calculator.
