Data URI images, base64 version of an image that is included in a file and is fetched in a single HTTP request, are mostly used for minimizing HTTP requests (which is great for speed).

Duri.me is a simple but very useful web application for creating Data URIs instantly.

In order to use it, just drag ‘n’ drop any image to the app and it’ll be converted. After that, you have the options to get the output as CSS, <img> or just the base64 text.
