Google Drive View-Only PDF Script Downloader

⚠️ Use only in desperate need — respect content creators’ rights. This script is meant for personal archiving when no other option exists.

Here you can use this script to download view‑only PDF files from Google Drive. This script works like a screenshot: it captures all PDF pages to a set of high‑resolution images and combines them into one PDF file.

📋 Instructions

  1. Open the PDF from Google Drive.
  2. Click Preview.
  3. On the top right page, click the three vertical dots menu → Open in new window.
  4. Scroll down the PDF to the very end and make sure all content is loaded.
  5. Inspect element (right‑click → Inspect) and go to the Console tab.
  6. If you’re using Chrome and cannot paste code directly, type allow pasting and press ENTER.
  7. Copy and paste the script below into the console, then press ENTER.
(function () {
  console.log("Loading script ...");

  let script = document.createElement("script");
  script.onload = function () {
    const { jsPDF } = window.jspdf;

    // Generate a PDF from images with "blob:" sources.
    let pdf = null;
    let imgElements = document.getElementsByTagName("img");
    let validImgs = [];

    console.log("Scanning content ...");
    for (let i = 0; i < imgElements.length; i++) {
      let img = imgElements[i];

      // specific check for Google Drive blob images
      let checkURLString = "blob:https://drive.google.com/";
      if (img.src.substring(0, checkURLString.length) !== checkURLString) {
        continue;
      }

      validImgs.push(img);
    }

    console.log(`${validImgs.length} content found!`);
    console.log("Generating PDF file ...");

    for (let i = 0; i < validImgs.length; i++) {
      let img = validImgs[i];
      
      // Convert image to DataURL via Canvas
      let canvasElement = document.createElement("canvas");
      let con = canvasElement.getContext("2d");
      canvasElement.width = img.naturalWidth;
      canvasElement.height = img.naturalHeight;
      con.drawImage(img, 0, 0, img.naturalWidth, img.naturalHeight);
      let imgData = canvasElement.toDataURL();

      // Determine orientation and dimensions for THIS specific image
      let orientation = img.naturalWidth > img.naturalHeight ? "l" : "p";
      let pageWidth = img.naturalWidth;
      let pageHeight = img.naturalHeight;

      if (i === 0) {
        // Initialize PDF with the dimensions of the FIRST image
        pdf = new jsPDF({
          orientation: orientation,
          unit: "px",
          format: [pageWidth, pageHeight],
        });
      } else {
        // For subsequent images, add a new page with THAT image's specific dimensions
        pdf.addPage([pageWidth, pageHeight], orientation);
      }

      // Add the image to the current page
      pdf.addImage(imgData, "PNG", 0, 0, pageWidth, pageHeight, "", "SLOW");

      const percentages = Math.floor(((i + 1) / validImgs.length) * 100);
      console.log(`Processing content ${percentages}%`);
    }

    // Check if title contains .pdf in end of the title
    let title = document.querySelector('meta[itemprop="name"]')?.content || document.title || 'download.pdf';
    if ((title.split(".").pop() || "").toLowerCase() !== "pdf") {
      title = title + ".pdf";
    }

    // Download the generated PDF.
    console.log("Downloading PDF file ...");
    pdf.save(title, { returnPromise: true }).then(() => {
      document.body.removeChild(script);
      console.log("PDF downloaded!");
    });
  };

  // Load the jsPDF library using the trusted URL.
  let scriptURL = "https://unpkg.com/jspdf@latest/dist/jspdf.umd.min.js";
  let trustedURL;
  if (window.trustedTypes && trustedTypes.createPolicy) {
    const policy = trustedTypes.createPolicy("myPolicy", {
      createScriptURL: (input) => {
        return input;
      },
    });
    trustedURL = policy.createScriptURL(scriptURL);
  } else {
    trustedURL = scriptURL;
  }

  script.src = trustedURL;
  document.body.appendChild(script);
})();
⏱️ Processing time depends on the PDF content (number of pages, resolution). Wait until the download prompt appears.

✨ Enjoy… but please, use it responsibly.

Choisir sa Province d’Affectation : Région Marrakech-Safi Choisir sa Province d’Affectation en tant qu’Enseignant — Région Marrakech-Safi Lorsqu’un enseignant est affecté dans la région Marrakech-Safi, il doit souvent choisir entre villes, bourgs et douars. Certains endroits offrent de bonnes conditions (logement, transport, proximité de la ville), tandis que d’autres sont plus difficiles (isolement, pauvreté des infrastructures). Voici une analyse par province avec des exemples concrets. Préfecture de Marrakech Description : La ville de Marrakech concentre tous les services. Mais certains enseignants sont envoyés dans des communes périphériques. Exemples favorables : Marrakech, Tassoultante, Saada (bonne accessibilité, logements, proximité de Marrakech). Exemples difficiles : Sidi Zouine, ouled dlim (villages périphériques mal desservis, transport scolaire compliqué). Province de Chichaoua Description :...
