Hesitant to post this since this has been asked before. But when I paste or upload (through the image button) a small image in the HTML editor demo, it does not result in a base64 image being included. This is a screenshot of the HTML after pasting an image (new image right at the top):
Hi @mrentier,
This particular editor is configured to upload images to a controller via the Url attribute. RadzenHtmlEditor embeds the pasted images as base64 only when the Url attribute is not set.
