Chat2pdf provides a way to export/backup chat history to PDF/JPEG (the chat app could be whatsapp/wechat/qq/line etc). It uses screen record + image processing to save the chat history into PDF file or long JPEG image.
Basic usage:
1. click record button and start to record chat history (when sliding screen, must keep the finger direction from bottom to top)
2. After record, click 'Convert PDF'/Convert JPEG' button to convert the screen record to PDF document or long picture/JPEG file.
3. View/share the generated PDF/JPEG.
Because only Android 5.0 above provides non-root screen record, so this application only supports Android 5.0 and above.
