APK Extractor is a Windows desktop application that enables you to extract APK and XAPK files from Android devices connected via ADB (Android Debug Bridge). It provides both a modern web interface and a command-line interface, giving you flexibility in how you work.

​
What is APK Extractor?

APK Extractor is a local tool that communicates with Android devices through ADB to:
  • Extract APK files from installed applications
  • Compile Split APKs into installable XAPK packages
  • Manage devices connected via USB or wireless debugging
  • Browse and search installed applications
The tool operates entirely on your local machine - no data is sent to external servers, and extracted files are never stored on a remote server.

​
Key Features

​
Device Management

Automatic Detection

Automatically detects Android devices connected via USB or WiFi with real-time monitoring

Wireless Debugging

Connect to devices over WiFi using Android 11+ wireless debugging with guided pairing

Saved Devices

WiFi devices are automatically saved for quick reconnection with easy rebinding when ports expire

Custom Names

Assign custom names to any device for easier identification across web and CLI interfaces

​
Application Extraction

  • Real App Names - Displays the actual application name (e.g., WhatsApp) alongside the package name (com.whatsapp)
  • Complete Information - Shows format (APK / Split APK) and exact file size for each app
  • Smart Filtering - Filter apps by type: user-installed, system, or all
  • Instant Search - Built-in search functionality to find apps by name or package
  • APK Extraction - Direct download of single APK files
  • XAPK Compilation - Packages Split APKs into a single installable .xapk file

​
Modern Web Interface

  • Responsive Design - Mobile-first design that adapts to phones, tablets, and desktops
  • Ultra-Fast Performance - 100% asynchronous server using parallel processing (Promise.all) to handle hundreds of apps in seconds
  • Intelligent Caching - Key routes, configurations, and app lists are cached in memory for instant device switching
  • Async Loading - Heavy operations (format and size detection) load in the background with progress indicators
  • Theme Support - Polished light and dark mode with vibrant colors and glassmorphism effects
  • System Tray - Background server with Windows system tray icon for easy access and control
  • Built-in Console - Real-time log viewer accessible from the web interface

​
Command-Line Interface

  • Color Output - Supports ANSI colors (cyan, green, yellow, red) for excellent readability
  • Interactive Menus - Robust menu system with native error handling and paginated navigation
  • 100% Accurate - Uses direct Android methods (du -b) to calculate exact format and size
  • Full Feature Parity - Saved devices, wireless connection, and custom naming available from CLI

​
Integrated ADB

  • Automatic Download - Downloads official Android Platform Tools if ADB is not found
  • Manual Configuration - Option to use an existing ADB installation on your system
  • Persistent Settings - Configuration is saved to config.txt for future sessions

​
Use Cases

Create backups of your installed applications before a factory reset, device migration, or OS upgrade. Extract APKs to keep a local copy of apps that may no longer be available in app stores.
Extract APKs from one device and install them on another without requiring app store access. Perfect for transferring apps to devices without Google Play Services or in offline environments.
Preserve specific versions of applications before updates. Useful for maintaining compatibility with specific workflows or for archiving purposes.
Extract APKs for analysis, reverse engineering, or testing purposes. Examine app structures, resources, and compiled Split APK configurations.

​
System Architecture

APK Extractor offers two parallel interfaces that share the same core functionality:

​
Web Interface (start-web.bat)

  • Backend: Express.js server (server.js) running on localhost:3000
  • Frontend: Static HTML/CSS/JS files served from the public/ directory
  • Communication: RESTful API with Server-Sent Events (SSE) for progress streaming
  • Process: Runs invisibly in background with system tray integration

​
CLI Interface (apk-downloader.bat)

  • Implementation: Pure Windows batch script with no dependencies
  • Execution: Direct ADB command execution with formatted console output
  • Independence: Fully functional without Node.js or web server
Both interfaces:
  • Use ADB as the core communication layer with Android devices
  • Share configuration files (config.txt, devices.json, device-names.json)
  • Support the same features with consistent behavior
