Frequently Asked Questions

What is a Data URI?+

A Data URI is a Base64 encoded image prefixed with its MIME type so it can be used directly as an image source in HTML or CSS without a separate file.

Should I Base64 encode large images?+

No. Base64 increases file size by ~33% and large encoded images slow down page load. Use it only for small icons and logos.

Will this work in all browsers?+

Yes. Data URI and Base64 image support is universal across all modern browsers.

What is the output of the CSS option?+

It outputs background-image: url('data:...'); ready to paste directly into your CSS stylesheet.
