The Image Encoder is a tool for converting images (or other binary files) into data URLs. A data URL has the prefix data: and is a convenient way to embed small files inline in documents.
The Image Encoder allows you to encode the actual images instead of having to dynamically fetch remote resources (that can be removed without notice). You can drag and drop the image you wish to convert onto the Insights Platform workspace. The image will appear in a new Image Encoder window. Alternatively, you can access the Image Encoder by selecting from the menu bar.
