Answer 1

Well to convert the image you need the image data otherwise there's nothing to convert. So the step for the most effecient would be.

1. Perform get request to the image url

2. Read all the bytes from the response body

3. Convert to base64

4. Save the base 64 string locally or use how you please.

You don't have to save it. Just keep in mind if the user closes the app or it stops at any point during this process you'll have to start it from the beginning because you're not saving the image to disk.
