Conversion of crypt12 files to pdf file format

Special utilities like the WhatCrypt Tools should be able to help you with a conversion / recovery of various WhatsApp message backups (for example .crypt12 files introduced as far as June/July 2016) and save the chat history in a ZIP compressed HTML file  that you can view in pretty much every web browser.

Once you have done that, you can use the default PDF export / print function in your web browser to get a PDF file of the chat history, essentially achieving crypt12 to pdf conversion.
