   • Method 2: Zoom in your browser (130-150%) before running the script
   • Method 3: Best for quick previews or when quality isn't critical

   • Output directory contains individual PDF directories
   • Each PDF directory contains a "Pages" folder with individual page images
   • Method 1 supports bulk PDF generation by placing multiple .PDF_DataFile in the Input directory

3. Troubleshooting:

   • If a PDF directory already exists, you'll be prompted to delete it
   • Press 'Y' to overwrite or 'N' to skip that specific file
   • Check the console for detailed progress and error messages
   • If you encounter issues, try refreshing the page and running the script again
