You don’t need the Blob for that, you can do it directly with
a.href = 'data:image/png;base64,' + file;.

Example:

var file = 'R0lGODlhDwAPAKECAAAAzMzM/////wAAACwAAAAADwAPAAACIISPeQHsrZ5ModrLlN48CXF8m2iQ3YmmKqVlRtW4MLwWACH+H09wdGltaXplZCBieSBVbGVhZCBTbWFydFNhdmVyIQAAOw==';
var a = document.createElement("a");
a.href = 'data:image/png;base64,' + file;
a.download = "informe um nome";
document.body.appendChild(a);
a.click();
$(window).on('focus', function(e) {
  $('a').remove();
});
