How do I convert the following remote URL to a base64 safe URL with C#?

Question

I want to fetch remote images and do some image transformation specifically an overlay over an image with cloudinary. But cloudinary only supports 64base safe urls to overlay images. Lets say I have this following remote image URL.

https://scontent.xx.fbcdn.net/v/t1.0-9/15665479_1260320054027269_4201232212927955955_n.jpg?oh=ee01f2ec47b2e972bc12f99d988db241&oe=5946A159

How can I encode it to a 64base url? I have been through many SO questions related to the question but none of them were helped me to solve the issue.

Do they need your URL to be encoded in Base64 or the image to be encoded? You can do both of them pretty easily.. — Rodrigo Vedovato, Feb 17 '17 at 11:32
They need the remote image URL not the image it self. So Can you help me with that? — BeanMRCode, Feb 17 '17 at 11:34

In case you need to encode both URL and Image (may not be what you need, but might be useful sometime)

string url = "https://scontent.xx.fbcdn.net/v/t1.0-9/15665479_1260320054027269_4201232212927955955_n.jpg?oh=ee01f2ec47b2e972bc12f99d988db241&oe=5946A159";

string encodedUrl = Convert.ToBase64String(Encoding.Default.GetBytes(url));

using (var client = new WebClient())
{
    byte[] dataBytes = client.DownloadData(new Uri(url));
    string encodedFileAsBase64 = Convert.ToBase64String(dataBytes);
}

I take this as answer as it does what I asked for but if you please have a look at the [following](http://stackoverflow.com/questions/39337286/overlay-a-fetched-image-over-itself-with-transformations-with-cloudinary) url and see if you can further help me with the issue. – BeanMRCode Feb 17 '17 at 11:55
