Questions tagged [data-uri]

A data URI is a URL whose scheme part is 'data:' and which directly represents a resource, rather than the location of a resource.

The following is an example of a data URI:

data:text/html;base64,PCFkb2N0eXBlIGh0bWw+CjxodG1sPgogIDxoZWFkPg

That data URI contains a HTML document. If pasted into the address bar of a compliant browser, the document it contains will be displayed without the need to request any external resources.

Data URIs can be used in the href or src attributes of <a> and <img> elements, etc., eliminating the need for additional HTTP requests.
