Here is an example of how you can get a Base64 encoded image using the ng-flow for the image upload, for instance, if you need to send the image in a JSON request. As you may have noticed, ng-flow returns a file object, however you still can get the Base64 string with the help of HTML5 FileReader:
1 2 3 4 5 6
Here, the base64 variable will contain the Base64 string of the image.
You can try it yourself on CodePen.
