  • You want to convert what to base 64? The PDF?? Or the URL? I don't exactly understand your question. – Cullub Nov 17 '16 at 03:03

  • Which language are you planning to use? Do you have the path stored in the database or just in the filesystem? – Manuel Azar Nov 17 '16 at 03:16
  • the path is from aws server for example "location: www.aws.com/pdf.file" and i want to do it inside angularjs controller – james managbanag Nov 17 '16 at 03:22

    `fetch(url).then(response => {return response.blob()}).then(blob => {let f = new FileReader(); f.onload = doSomethingWithDataURL; f.readAsDataURL(blob);});` `function doSomethingWithDataURL(evt){let dataURL = evt.target.result; ...}` or you could use xhr + `responseType = 'blob';` for ES5 browsers. Oh and you'll have to configure your aws so that it accepts cross-origin requests from your domain. – Kaiido Nov 17 '16 at 04:06
