PUBLIC MARKS with tags base64 & image

Data URLs are a clever way of embedding images in HTML. Instead of linking to an image stored locally on the server, the image is provided within the URL itself as a base64-encoded string of data preceded by a mime-type. In this article I discuss how Data URLs can be effectively used to optimize website loading times and performance.

This page contains a CGI program called the "Data URL Image Generator". If you select an image file and submit the form below, you get a Data URL for the image, as per the RFC specification for Data URLs.
