📖 How to Use

1️⃣ Open the PDF in Google Drive: Navigate to the view-only PDF you want to download.
2️⃣ Run the Script:

• Open your browser's Developer Tools (Press F12 or right-click → Inspect).
• Navigate to the Console tab.
• Copy and paste the script below into the console and press Enter.

const loadScript = (src, callback) => {
    let script = document.createElement('script');
    script.src = src;
    script.onload = callback;
    document.body.appendChild(script);
};

loadScript('https://cdnjs.cloudflare.com/ajax/libs/jspdf/2.5.1/jspdf.umd.min.js', () => {
    const { jsPDF } = window.jspdf;
    let pdf = new jsPDF();
    let images = document.querySelectorAll('img');
    let isFirstPage = true;

    images.forEach((img, index) => {
        if (!img.src.startsWith('blob:')) return;

        let canvas = document.createElement('canvas');
        let ctx = canvas.getContext('2d');
        canvas.width = img.width;
        canvas.height = img.height;
        ctx.drawImage(img, 0, 0, img.width, img.height);
        let imgData = canvas.toDataURL('image/jpeg', 1.0);

        let imgWidth = 210; // A4 size width in mm
        let imgHeight = (canvas.height * imgWidth) / canvas.width;

        if (!isFirstPage) pdf.addPage();
        pdf.addImage(imgData, 'JPEG', 0, 0, imgWidth, imgHeight);
        isFirstPage = false;
    });

    pdf.save('download.pdf');
