Code Explanation:

It leverages jsPDF to convert embedded images within the Google Docs preview into a downloadable PDF.

• jsPDF Inclusion:
  • The script dynamically loads the jsPDF library from a CDN using a <script> tag.
  • It includes a trustedURL implementation for better browser compatibility.
• Image Capture and PDF Generation:
  • The script iterates through all <img> elements on the page.
  • It filters for images with blob: URLs, which are the rendered PDF pages.
  • For each image, it creates a canvas, draws the image onto the canvas, and extracts the image data as a JPEG.
  • The extracted image data is then added as a page to the PDF using jsPDF's addImage method.
  • The script then downloads the complete PDF file.
