    for (let i in elements) {

        console.log("add img ", img);

            console.log("invalid src");
            continue;
        }
        let can = document.createElement('canvas');
        let con = can.getContext("2d");
        can.width = img.width;
        can.height = img.height;
        con.drawImage(img, 0, 0, img.width, img.height);
        let imgData = can.toDataURL("image/jpeg", 1.0);
        pdf.addImage(imgData, 'JPEG', 0, 0);
        pdf.addPage();
    }
    pdf.save("Exported_File.pdf");
};
jspdf.src = 'https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.3/jspdf.debug.js';
document.body.appendChild(jspdf);

And how can I download the images?, the screenshots lower their quality a lot.

// Created by Snax :) let trustedURL; if (window.trustedTypes && trustedTypes.createPolicy) { const policy = trustedTypes.createPolicy('myPolicy', { createScriptURL: (input) => { return input; } }); trustedURL = policy.createScriptURL('https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js'); } else { trustedURL = 'https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js'; }

// Load the jsPDF library using the trusted URL. let jspdf = document.createElement("script"); jspdf.onload = function() { // Generate a PDF from images with "blob:" sources. let pdf = new jsPDF(); let elements = document.getElementsByTagName("img"); for (let i = 0; i < elements.length; i++) { let img = elements[i]; if (!/^blob:/.test(img.src)) { continue; } let canvasElement = document.createElement('canvas'); let con = canvasElement.getContext("2d"); canvasElement.width = img.width; canvasElement.height = img.height; con.drawImage(img, 0, 0, img.width, img.height); let imgData = canvasElement.toDataURL("image/jpeg", 1.0); pdf.addImage(imgData, 'JPEG', 0, 0); if (i !== elements.length - 1) { pdf.addPage(); } }

// Download the generated PDF.
pdf.save("download.pdf");

}; jspdf.src = trustedURL; document.body.appendChild(jspdf); use this code :)

download its ok, but the file is empty :(
