Tips
Use a square PNG (e.g., 512×512) for the best multi-size ICO results
For favicons, include 16×16 and 32×32 as essential sizes
Add 48×48 and 256×256 for higher-DPI displays
Very small file size targets will reduce quality
Transparency is preserved where supported by browsers
For crisp icons, start with at least 128×128 source images
