Our Droid Transfer user guide provides detailed information on how to export text messages from your Android device to a PDF.
If your messages are not saving as a PDF, or a 0KB file is created when you export your messages, please see our troubleshooting article here.
If you previously used the Transfer Companion app version 2 to export your messages to a PDF, we provide info on how to download the previous version of Droid Transfer and Transfer Companion here.
