BMP to ICO
Installer-era artwork
Legacy branding kits ship 256×256 BMP squares for splash screens. When those same assets must become multi-resolution ICO sets for shortcuts or PWA shells, convert here—then validate each embedded size because nearest-neighbor scaling from one BMP can look chunky.
Modern alternative
Where possible, rebuild icons from SVG masters; raster BMP→ICO is a compatibility bridge, not a quality upgrade. Extract layers via ICO to PNG when you need to edit.
