Use vector graphics (SVG, AI, EPS, PDF) as the source
Design at the exact cursor size you need
Keep shapes simple and clean
Use crisp edges and avoid tiny details
Export at the highest practical resolution
Use transparent backgrounds
Convert to PNG only if the cursor format requires it
Save multiple sizes for different display scales
Use nearest-neighbor or lossless export settings when scaling pixel art
Avoid repeated resizing after export
Use anti-aliasing carefully to preserve edge quality
Test on different screen resolutions and DPI settings
If making animated cursors, keep each frame sharp and consistent
Use cursor-specific formats like CUR, ANI, or platform-supported formats
Keep the hotspot aligned precisely
Re-export from the original source instead of editing compressed files
