  AsposePDFWebWorker.onerror = evt => console.log(`Error from Web Worker: ${evt.message}`);
  AsposePDFWebWorker.onmessage = evt => document.getElementById('output').textContent = 
    (evt.data == 'ready') ? 'loaded!' :
      (evt.data.json.errorCode == 0) ? `Result:\n${DownloadFile(evt.data.json.fileNameResult, "application/msword", evt.data.params[0])}` : `Error: ${evt.data.json.errorText}`;

  /*Event handler*/

    const file_reader = new FileReader();
    file_reader.onload = event => {
      /*Convert a PDF-file to Doc and save the "ResultPDFtoDoc.doc" - Ask Web Worker*/
      AsposePDFWebWorker.postMessage({ "operation": 'AsposePdfToDoc', "params": [event.target.result, e.target.files[0].name, "ResultPDFtoDoc.doc"] }, [event.target.result]);
    };
    file_reader.readAsArrayBuffer(e.target.files[0]);
  };

  /*Make a link to download the result file*/
  const DownloadFile = (filename, mime, content) => {
      mime = mime || "application/octet-stream";
      var link = document.createElement("a"); 
      link.href = URL.createObjectURL(new Blob([content], {type: mime}));
      link.download = filename;
      link.innerHTML = "Click here to download the file " + filename;

Simple example:

  var ffileToDoc = function (e) {
    const file_reader = new FileReader();
    file_reader.onload = (event) => {
      /*Convert a PDF-file to Doc and save the "ResultPDFtoDoc.doc"*/
      const json = AsposePdfToDoc(event.target.result, e.target.files[0].name, "ResultPDFtoDoc.doc");
      if (json.errorCode == 0) document.getElementById('output').textContent = json.fileNameResult;
      else document.getElementById('output').textContent = json.errorText;
      /*Make a link to download the result file*/
      DownloadFile(json.fileNameResult, "application/msword");
    }
    file_reader.readAsArrayBuffer(e.target.files[0]);
