Online tool for extracting content of Android ADB backup files and repacking selected parts into separate backup file.
Note: This tool is completely client-based and all processing is done on your device. That means your files are not transferred to the server.
If you you're an Android enthusiast that likes to learn more about Android internals, I highly recommend to check out the Bugjaeger app. It allows you to connect 2 Android devices through USB OTG and perform many of the tasks that are normally only accessible from a developer machine via ADB directly from Android phone/tablet.
