Device support
For Apple devices with the IOS Operating Sysytem version 1.1.3 or later, such as the iPod Touch, iPhone, and iPad, as well as some Android devices, it is possible to provide a custom icon that users can display on their Home screens using the Web Clip feature (called Add to Home Screen within Mobile Safari). This feature is enabled by supplying a <link rel="apple-touch-icon" ...> in the <head> section of documents served by the web site. If the custom icon is not provided, a thumbnail of the web page will be put on the home screen instead.The recommended basic size for this icon is 60×60 pixels; for best display on the higher-resolution iPhone 4 screen, an icon size of 120×120 pixels is recommended.For the iPad and iPad 2, the basic size is 76×76 pixels. For the 3rd generation i-pad , the high-resolution size would be 152×152 pixels. Android tablets [via Chrome] prefer a 192x192 PNG icon.The icon file referenced by apple-touch-icon is modified to add rounded corners, drop shadow, and reflective shine. Alternatively, an apple-touch-icon-precomposed icon may be provided to instruct devices not to apply reflective shine on the image .Why it is Required ?
According to me it should be compulsory or it is ,because it helps us to find our desired or requiring Website in Web Browser. when it contains so much of open websites and files at the time . so Favicon helps to Recognize Website.andThere is many .ico file generator available on web/Internet.where you can change your .PNG file into .ICO fileThank you
