About Icon Files
ICO files are container files that can include multiple images at different sizes and color depths. A good ICO file should contain multiple sizes for optimal display across different platforms.
Tips for Best Results
→
Include all standard sizes in a single ICO file
→
Use PNG format within the ICO for better transparency
→
Use 32-bit color depth (24-bit + 8-bit alpha channel)
→
Design with simple, bold shapes for small sizes
→
Test your icon on different backgrounds
Standard Icon Sizes
When designing icons for various platforms and devices, it's important to consider different icon sizes to ensure optimal display across different resolutions and environments. Below are the standard icon sizes and their common uses:
16×16 pixels - Toolbar, Address bar, Favorites
32×32 pixels - Shortcut icons, Desktop, Explorer
48×48 pixels - Windows Explorer, Start Menu
64×64 pixels - Windows Vista, 7, 8, 10
128×128 pixels - High-resolution displays, macOS
256×256 pixels - Windows 10, macOS, High-DPI displays
Key Points About ICO Files
An ICO file can contain multiple images of different sizes (e.g., 16×16, 32×32, 48×48, etc.)
Each image in the ICO can be either in BMP or PNG format
BMP format was the original format, but doesn't support alpha transparency well
PNG format was added later (in Windows Vista) and supports full alpha-channel transparency
Modern icons typically use PNG format internally for better transparency
Each image in an ICO file can have different bit depths (1, 4, 8, 24, or 32 bits per pixel)
32-bit images have 24 bits for color and 8 bits for an alpha channel (transparency)
