Favicon Generator Advanced
PNG pack: 16, 32, 48, 64, 180, 192, 512 plus a simple ICO.
Favicon Generator Advanced is its own job in the catalog (utilities): PNG pack: 16, 32, 48, 64, 180, 192, 512 plus a simple ICO. It is not a copy of the resizer or converter with a new title — the operation is “favicon-adv”.
