About 裁剪图片
Crop an image to a selected rectangular area. Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.
Crop for composition before you optimize size
Cropping removes pixels you do not need and changes the composition at the same time. Decide the final aspect ratio based on the destination—square thumbnail, portrait card, document image or custom frame—before exporting.
Keep important faces, labels and focal points away from the extreme edges because some platforms add their own rounded corners or responsive cropping.
A realistic example
For a square profile image, place the subject near the center and leave a little breathing room rather than cropping tightly to the face.
When this tool is not the right fit
Cropping cannot fix a source where the important subject is already cut off.
