- Use 16:9 or 4:3 for desktop wallpapers, presentations, and landscape banner images.
- Crop away unwanted borders before running image compression or resizing.
Troubleshooting & Common Issues
- Crop box is stuck at fixed proportion: Switch the Aspect Ratio dropdown to Freeform if you need unconstrained width/height.
- Cannot select small detail: Use the workspace zoom slider to enlarge the canvas before positioning crop handles.
