Download all the .pdf links inside of a page, Console JS Script

1. Loads JSZip library from CDN
2. Finds all PDF links on the page
3. Fetches each PDF file
4. Adds them all to a single ZIP file
5. Downloads the ZIP file as pdfs.zip

// Load JSZip library
const script = document.createElement('script');
script.src = 'https://cdnjs.cloudflare.com/ajax/libs/jszip/3.10.1/jszip.min.js';
script.onload = async function() {
  console.log('JSZip loaded, collecting PDFs...');
  
  // Find all PDF links
  const pdfLinks = Array.from(document.querySelectorAll('a'))
    .filter(link => link.href.toLowerCase().includes('.pdf'))
    .map(link => link.href);
  
  console.log(`Found ${pdfLinks.length} PDF files`);
  
  if (pdfLinks.length === 0) {
    console.log('No PDF files found on this page');
    return;
  }
  
  // Create zip file
  const zip = new JSZip();
  
  // Download each PDF and add to zip
  for (let i = 0; i < pdfLinks.length; i++) {
    try {
      console.log(`Downloading ${i + 1}/${pdfLinks.length}: ${pdfLinks[i]}`);
      const response = await fetch(pdfLinks[i]);
      const blob = await response.blob();
      const filename = pdfLinks[i].split('/').pop().split('?')[0] || `document_${i}.pdf`;
      zip.file(filename, blob);
    } catch (error) {
      console.error(`Failed to download ${pdfLinks[i]}:`, error);
    }
  }
  
  // Generate and download zip
  console.log('Creating ZIP file...');
  const zipBlob = await zip.generateAsync({type: 'blob'});
  const a = document.createElement('a');
  a.href = URL.createObjectURL(zipBlob);
  a.download = 'pdfs.zip';
  document.body.appendChild(a);
  a.click();
  document.body.removeChild(a);
  console.log('Done! Check your downloads folder for pdfs.zip');
};
document.head.appendChild(script);
