Images as Base64 Data URIs

Drop an image and get a data URI, raw Base64, an <img> tag or a CSS background rule - or paste Base64 back to preview and download the image. Conversion runs locally; the image is never uploaded anywhere.

A Base64-encoded image is about 33% larger than the binary file and skips HTTP caching, so the technique only pays off for small assets: icons of a few kilobytes, email templates, single-file HTML documents. Where the break-even actually sits is measured in images and Base64 data URIs. For encoding text rather than files, use the Base64 encoder.
