Avoid Complex Images
Photographs and detailed images don't scale well to small sizes. Use simple logos, icons, or graphics instead.
Test Multiple Sizes
Always test your icons at different sizes to ensure they remain clear and recognizable, especially at 16x16 and 32x32.
Optimize File Size
Use appropriate color depth (8-bit for simple icons, 32-bit only when transparency is needed) to keep file sizes small.
Use Vector Sources
When possible, create icons from vector formats (SVG, AI) and convert to ICO for the best quality at all sizes.
