WeChat(微信), as the most popular mobile IM app in China, doesn't give users any method to export well-formatted history message. This tool can parse and export WeChat messages on a rooted android phone.

Right now it can dump messages in text-only mode, or generate a single-file html containing voice messages, images, emoji, etc.

NEWS: WeChat 6.0+ uses silk to encode audio. The code is updated.

NEWS: WeChat 6.3 uses a new avatar storage. The code is updated.

If this tools works for you, please take a moment to add your phone/OS to the wiki. If it doesn't work, please leave an issue together with your phone/OS/wechat version.

• python-PIL
• PyQuery
• pysox
• pysqlcipher
• numpy
• python-csscompressor (suggested, optional)
• adb and rooted android phone connected to a Linux/Mac OS.
• Silk audio decoder (just run ./third-party/compile_silk.sh)
• gnu-sed

• Get decrypted WeChat database (Linux & Mac Only):
  • Automatic: ./android-interact.sh db-decrypt
    • Requires rooted adb. Available at https://play.google.com/store/apps/details?id=eu.chainfire.adbd&hl=en
  • Manual:
    • Get /data/data/com.tencent.mm/MicroMsg/long-long-name/{EnMicroMsg.db,sfs/avatar.index} from root filesystem, possible ways are:
      • ./android-interact.sh db
      • Use your rooted file system manager app
    • Get WeChat uin, possible ways are:
      • ./android-interact.sh uin
      • Login to web wechat, get wxuin=1234567 from document.cookie
    • Get your phone IMEI number, possible ways are:
      • ./android-interact.sh imei
      • Call *#06# on your phone
      • Find IMEI in system settings
    • Decrypt database, will produce decrypted.db:

     ./decrypt-db.py <path to EnMicroMsg.db> <imei> <uin>
    

NOTE: you may need to try different ways to getting imei & uin, because things behave differently on different phones.

Also, if the decryption doesn't work with pysqlcipher, maybe try the version of sqlcipher in legacy.

• Get WeChat user resource directory from your phone to resource directory:
  • ./android-interact.sh res
  • You might need to change the resource location in this script if the default doesn't work
  • This takes a long time.

• Parse and dump text messages of every contact (resource directory is not needed to run this):

./dump-msg.py decrypted.db output_dir

• Generate statistical report on text messages:

./count-message.sh output_dir

• Dump messages of one contact to html, containing voice messages, emojis, and images:

./dump-html.py decrypted.db avatar.index resource <contact name> output.html

See here for an example html.

Screenshots of generated html:

• Search by uid/username
• Faster way to copy a directory from android (I don't know..).
• Fix rare unhandled types: > 10000 and < 0
• Better user experiences... see grep 'TODO' wechat -R
• more easy-to-use for non-programmers (GUI?)
