4. Add custom sizes if needed with specific dimensions (up to 4 custom sizes)
5. Decide whether to maintain square aspect ratio (recommended) or use custom width/height

About ICO Files

The ICO file format is a specialized container designed specifically for icons:

• Multiple Sizes: A single ICO file can contain multiple images at different resolutions
• Automatic Selection: Operating systems and browsers automatically select the most appropriate size
• Transparency Support: ICO files support alpha transparency for modern-looking icons
• Bit Depth Options: Support for various color depths from 1-bit (2 colors) to 32-bit (16.7M colors with alpha)

Why Use Multi-Size ICO Files?

Including multiple sizes in your ICO files provides several benefits:

• Better display quality across different screen resolutions and zoom levels
• Appropriate sizes for taskbars, file browsers, and desktop shortcuts
• Improved scalability on high-DPI displays
• Faster rendering as the system doesn't need to resize icons on the fly
