Your approach is wrong.
The readAsDataURL method is used to read the contents of the specified Blob or File.
The result will be base64 encoded string.
The readAsDataUrl method can be used to make a image preview.
To download the file you can go by this approach
<!DOCTYPE html>
<html>
<head> </head>
<body>
<form>
<label for="file">ChooseFile</label>
<input type="file" id="myFile" accept="image/*">
</form>
<script>
document.getElementById("myFile").addEventListener("change", downloadFile);
function downloadFile() {
let file = this.files[0];
let url = URL.createObjectURL(file);
let link = document.createElement('a');
link.href = url;
link.download = file.name;
link.click();
link = null;
URL.revokeObjectURL(url);
}
</script>
</body>
</html>
