Tips for Method 1 ​

  • You should always give a custom file name by changing the place holder "Document" to "Cool_File_Name" in Method_1_Script.js. Do not include ".pdf" file extension along with the document name here!
let pdfDocumentName = "Document";

Change to this

let pdfDocumentName = "Cool_File_Name";
  • By default this script will download PDF file with the highest quality available, but just in case if you need even better quality simply zoom in your browser (eg: 200% to 300%) then follow the above steps to download.
  • The Output directory contains individual PDF directories for efficient organizing and "Pages" directory is present in each one of these.
  • The "Pages" directory contains individual pages of PDF document in .png format.
  • For bulk PDF generation, download all ".PDF_DataFile" for your viewonly PDF documents and copy these inside "Input" directory then double click on "GeneratePDF.cmd" to execute (For Linux execute "GeneratePDF" which is inside the "Linux" directory).
  • During execution of "GeneratePDF.cmd", PDF directory will be creates inside "Output" directory based on the custom "pdfDocumentName" given earlier. If the PDF directory name already present in "Output" directory, then it will ask user's permission to delete it. Just Press "Y" for YES or "N" for NO. If you press N then it will skip processing of that specific ".PDF_DataFile" and it's PDF won't be generated.

  3. Then open the browser web console.
  4. Paste the copied script into the console and press enter.
  5. After few seconds the browser will prompt you to save the PDF file.
  6. Save the file and enjoy!

Tips for Method 2 ​

  • You should give a custom file name by changing the place holder "Document" to "Cool_File_Name" in "Method_2_Script.js". Do not include ".pdf" file extension along with the document name here!
let pdfDocumentName = "Document";

Change to this

let pdfDocumentName = "Cool_File_Name";
  • By default this script will download PDF file with the highest quality available, but just in case if you need even better quality simply zoom in your browser (eg: 130% to 150%) then follow the above steps to download. If you increase the zoom level more than 150% Method_2_Script.js will struggle to generate the PDF.
