Frequently Asked Questions

What is a Data URI?

A Data URI stores file data directly inside a text string, allowing small images to be embedded in HTML or CSS without a separate image request.

Should I use Data URIs for large images?

Usually not. Large images create very long strings and can increase the size of your HTML or CSS significantly.

Are my images uploaded?

Your image is processed directly in your browser instead of intentionally uploading it to a Tool Digital Hub server.
