    I would suggest going another route, due to Browser compatibility. – StackSlave May 29 '18 at 06:40

Here is an Example how you can download your file Object.

But this will return nothing since the file size is too small for the system to read.

function downloadFile() {

 var file = new File(["aa"], "dek_iv.txt");
    var link = document.createElement("a");
    link.download =file.name;
    link.href = file;
    link.click();
}
<button onclick="downloadFile()">Download File</button>

  • You need to use some libraries if you want the HTML contents in a PDF file. – Harish Soni May 29 '18 at 07:06

  • "But this will return nothing since the file size is too small for the system to read." can you expand on this? i can't find any reference to a minimum file size – Jarry Jan 15 '19 at 16:50
