FaviconJapan - a service for creating and collecting website icon files.

As can be seen from the title, this is a Japanese service. Here, you can either upload your own images to generate corresponding icon files or download various types of icon files. If you want to upload your own images, only three formats are allowed: GIF, JPG, and PNG. After the icon file is generated, a segment of code will be provided. You just need to add it to your webpage to use the icon.
