There is a workaround method to export an entire Cloud Chat history to PDF from a computer.

The PDF will be text searchable, while maintaining the chat layout, text colours, and even emoji. But images and files will not be exported into the PDF (they will show up as blank).

This method depends on the Google Chrome browser, but it may work on other browsers.

Export Chat History Steps

  1. Launch Google Chrome on a computer
  2. Login to Telegram Web
  3. Select the Cloud Chat you want to export
  4. Click on the chat area so you can scroll through the chat history using your keyboard
  5. Hold down the Home button on keyboard to scroll to the beginning of the Chat History (this may take a while for large chats)
  6. When you reached the beginning of the Chat History, press the End button on keyboard to go back to the bottom of the chat
  7. Drag your mouse to highlight the most current section of the chat, from bottom to top
  8. With the highlighted text starting at the bottom of the chat, press Control + Shift + Home buttons. This will automatically select the rest of the entire Chat History, all the way to the very beginning.
  9. Right click > Print (or CTRL+P)
  10. Change Destination to Save as PDF
  11. Enable Background graphics and Selection only
  12. Click the Save button to export to a PDF file
  13. You will now have a text searchable PDF export of your Cloud Chat History.
