How to convert base64 string to binary-file and store on sftp

I’ve the same issue. I’m trying to convert a existing base64 "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA... onto image.

I did the same thing above.

HTTP > Parse > Variable ({{toBinary(10.value; “base64”)}}) > Google Drive

The image come broken.
