 * A plugin that converts images inserted into the editor into [Base64 strings](https://en.wikipedia.org/wiki/Base64)

 * This kind of image upload does not require server processing – images are stored with the rest of the text and
 * displayed by the web browser without additional requests.

 * Check out the {@glink features/images/image-upload/image-upload comprehensive "Image upload overview"} to learn about
