WhatsApp Data Import for Signal Android
This is a fork of the private messaging app Signal with the goal to provide a method to import WhatsApp conversations and facilitating the transition from WhatsApp to Signal.
You can find the original project at: https://github.com/signalapp/Signal-Android
It’s based on the fork of johanw666: https://github.com/johanw666/Signal-Android
WhatsApp Data Import
This fork of the Signal App aims at providing a method to import one’s WhatsApp conversations. It’s currently still a pretty tedious process, but at least it’s possible.
What works

  • Import 1-to-1 text conversation threads.
  • Import group chat conversations if a group chat with the same name is set up in the Signal App.
  • Importing images and videos messages from WhatsApp chats.

What doesn’t work

  • Multimedia messages other than images and videos are currently not imported.
  • It’s pretty slow (10 seconds per 1000 messages).

How to do it

  • Extract your unencrypted msgstore.db from your WhatsApp installation. There are several methods to do so. WhatsAppDump seems to offer a possibility that doesn’t require rooting the device. A more detailed description of how to do so might be added here in the future.
  • Copy the msgstore.db file to the top level directory of your internal storage
  • Make an encrypted Backup of your Signal Messages using the built-in feature of the Signal App.
  • Build and install this version of the Signal App and import the encrypted Backup of your signal messages.
  • You might have to go to the app permission settings and give it the permission to manage all of the external storage.
  • Go to Backup => Import WhatsApp to start the import.
  • Be patient until it finishes.
  • If you’re happy with the WhatsApp import create another encrypted backup of all Signal messages.
  • Install the original Signal app again and import the encrypted Backup.
