Usage Tips
Lock Aspect Ratio
When using custom dimensions, set the width and height and click the "Lock" button to maintain a fixed aspect ratio during cropping, preventing distortion.
Use Match Rate Score
After selecting a preset, the right panel will display a match rate score between your current crop area and the target dimensions. Higher scores indicate closer matches to the ideal size.
Rotation and Flipping
For horizontal images that need to be displayed vertically, use the rotation function; if you need a mirror effect, use the horizontal or vertical flip functions.
Reset Function
If you encounter issues during adjustment, click "Reset Crop" to restore to the initial state, or click "Upload Image" to upload a new image.
