Notes

Win8/IE10+ and iOS Safari support other types of icons for webpages too, using alternate tags.

See also SVG favicons.

  1. If both ICO and PNG are available, will use ICO over PNG if ICO has better matching sizes set.

  2. If both ICO and PNG are available, will ALWAYS use ICO file, regardless of sizes set.

  3. If multiple formats are available, will use the last one loaded, regardless of sizes (effectively picks at random).

  4. Does not use favicons at all (but may have alternative for bookmarks, etc.).

Bugs

  • IE 11 lost the support for non-RGB/a PNG format images inside FavIcon.ico, does work in IE 10.
