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.

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:

Key Points About ICO Files

An ICO file can contain multiple images of different sizes (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)
