data: URI Generator The data: URI scheme allows you to build URLs that embed small data objects. data: URIs are supported by most modern browsers except for Internet Explorer. The lack of IE support is holding back widespread adoption of data: URIs, but they are still very useful in a couple of specific areas such as embedding graphics and other data items in Greasemonkey scripts. You can read more about data: URIs and see some examples of their use, or use the generator below to create your own. data: URIs are defined in RFC 2397.
