How it works

Every ticked size is embedded in one .ico file; Windows and browsers pick the best size automatically.
Sizes are rendered from the WebP at their true pixel size, so small sizes stay crisp rather than being scaled-down bitmaps of a huge image.
WebP can have transparency; the chosen background colour is used behind transparent pixels because the classic ICO format has no alpha in some contexts.
The icon is built in your browser - the image is never uploaded.
