⚖️ Technical Format Comparison: ICO vs BMP
Detailed side-by-side analysis of compression algorithms, color depth, transparency, and file size impact
| Technical Specification | ICO (Source) | BMP (Target) |
|---|---|---|
| Full Format Name | Windows Icon File Container | Bitmap Image File (Microsoft Windows) |
| MIME Type | image/x-icon | image/bmp |
| Compression Method | Embedded Multi-Resolution PNG / BMP bitstreams | Uncompressed (Raw RGB Raster Grid or RLE) |
| Color Space & Bit Depth | 32-bit (24-bit RGB + 8-bit Alpha Channel) | 1-bit to 32-bit (typically 24-bit TrueColor) |
| Alpha Transparency | Yes (Full transparency preserved in modern 32-bit ICO) | No (Standard 24-bit BMP has no alpha channel) |
| Animation Support | No (Static multi-resolution container) | No (Static Single Frame) |
| Typical File Size | Small (Stores 16x16, 32x32, 48x48 icon pixel layers) | Very Heavy (Full uncompressed byte-for-byte pixel array) |
| Ideal Applications | Website browser tab favicons, Windows desktop application shortcuts | Raw uncompressed raster storage, legacy Windows apps, hardware displays |
💡 Conversion Impact Summary:
Decodes ICO into an uncompressed 24-bit TrueColor raster grid with standard BMP headers.
