PNG to ICO FAQ
Which sizes should a favicon include?
16 and 32 pixels cover browser tabs and bookmarks. Add 48 for Windows shortcuts and 256 for large desktop icons.
Is transparency kept?
Yes. Each size is stored as a PNG inside the ICO, so transparent backgrounds stay transparent.
What if my image is not square?
It is centered inside a square icon with transparent space on the sides, so nothing is stretched.
Will the ICO work on Windows?
Yes. PNG-based ICO files work on Windows Vista and later and in every modern browser.
