You can also change the page order: "1, 0, 2-8", clone required pages: "0, 0, 3, 3, 3", specify external pdf file as source: "0-3, [file:fileid_1]0-3, [file:fileid_1]5-7, [file:fileid_2]0-3" (see examples for details), or rotate page(s): await viewer.save("test_part10.pdf", { reload: true, pages: "[angle:90]2-3" });

  Example

  // Save six pages with indices: 0, 1, 2, 3, 7, 9:
  await viewer.save("test_part10.pdf", { reload: true, pages: "0-3, 7, 9" });
  

  Example

  // Rotate 90 degrees and save 2 pages with indices 2 and 3:
  await viewer.save("test_part10.pdf", { reload: true, pages: "[angle:90]2-3" });
  

  Example

  // Invoke the system file picker dialog 
  // to select an external PDF file to merge.
  // Then, merge first page from selected PDF document and
  // download result PDF file to local system.
  var fileInput = document.createElement('input');
  fileInput.type = 'file';
  fileInput.accept = ".pdf";
  fileInput.style.display = 'none';
  fileInput.onchange = function () { 
      if (fileInput.files && fileInput.files[0]) {
          var fileReader = new FileReader();
          fileReader.onload = function () {
              const fileId = "uniquefileid_" + new Date().getTime();
              viewer.storage.setItem(fileId, new Uint8Array(fileReader.result));
              // Merge first page from external PDF document 
              // to the end of the active PDF document
              // and download result PDF file:
              await viewer.save("sample.pdf", 
                  { pages: `0-${viewer.pageCount - 1}, [file:${fileId}]0`  });
          };
          fileReader.readAsArrayBuffer(fileInput.files[0]);
      }
  };
  document.body.appendChild(fileInput);
  fileInput.click();
