Online Favicon Grabber
Favicons of social networking websites can be used on our blogs, websites etc as bookmarking icons. You don’t have create new ones, infact I prefer using the default favicon. You see the Twitter favicon in the sidebar.
Mindzilla Icon Grabber is a free online utility that retrieves the shortcut icon for a selected web page and converts the icon into a more useful format.
Grabbing a favicon from your favourite website is just like 1, 2, 3. Just enter the URL of the website whose favicon you want, select the output favicon format and press the Grab It! button.
You will be able to save the favicon from the Output box in the right side.
