I came to know about FileReader API with HTML 5. Is there any way to work using that??. It should work on a local file.

Does Chrome Extension support FileReader API without running a localhost server ??

Answer 1

I found the answer myself. Chrome Extensions does support FileReader API of HTML 5. So just the code below works simple.

  var reader = new FileReader();
  reader.readAsDataURL(f);
