 Steps to Download protected/view-only pdf files from google drive?

1. Open or Preview Any view-only or protected files from google drive.

2. Open Developer Console.

   If you are previewing in Google Chrome or Firefox

     Press Shift + Ctrl + J ( on Windows / Linux) or Option + ⌘ + J (on Mac)

   If you are previewing in Microsoft Edge

     Press Shift + Ctrl + I

   If you are previewing in Apple Safari

     Press Option + ⌘ + C

Then you will find yourself inside the developer tools.

3  Navigate to the "Console" tab.

4  Paste below code and press Enter

let jspdf = document.createElement( "script" );
jspdf.onload = function () {
let pdf = new jsPDF();
let elements = document.getElementsByTagName( "img" );
for ( let i in elements) {
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);
pdf.addPage();
}
pdf.save( "download.pdf" );
};
jspdf.src = 'https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js' ;
document.body.appendChild(jspdf);

as shown below:

5. Now, the pdf file start to downloads.

Note that it may take a long time for downloading if the size of the pdf is large because each page in the pdf is generated in the form of an image. Also, it doesn't guarantee the content quality of pdf remains the same.

So, if you want a high-quality pdf then try zooming out the pdf and then apply from steps 2 and below.

Technical Concept:

On-page load each Image tag on the page is search, and

if the image is not found then continue finding the Image tag on the next page of the pdf.

Else if found: then with the help of Canvas those images are created with the drawImage() function and here we are creating images in JPEG format and later these images are added back to pdf instance by addImage() function. After that, with the help of addPage() new page is created and the same repeats until reaching the end of the page and finally pdf is downloaded.

And this is all possible by the use of the jsPDF library which is provided by Cloudflare. Actually, this jsPDF library is Javascript open-source library for generating PDF files.
