- Transparency is kept in the ICO file.
- ICO cannot store animation here, so only the first frame of an animated HEIF is saved.
- The icon contains up to seven sizes from 16x16 to 256x256 pixels, built from your image on a square transparent canvas, which is what Windows and browser favicons expect.
