When downloading Android apps outside the Google Play Store, you may come across different file formats like APK, XAPK, or OBB. But what do they mean? And how do you install them correctly?

In this guide, we’ll explain the difference between APK, XAPK, and OBB files — and show you how to install each type safely and easily.

🧩 What Is an APK File?

APK (Android Package Kit) is the standard file format for installing apps on Android devices.

✅ Key Features:

• Single file (e.g., appname.apk)
• Installs like any other app
• Common for simple or smaller apps

📥 How to Install:

1. Download from a trusted source (like apkjut.online)
2. Enable “Install Unknown Apps” in settings
3. Tap the APK to install it
4. Done!

📦 What Is an XAPK File?

XAPK is a compressed file format that includes:

• The APK file (installer)
• OBB file (data file)
• Other assets (e.g., images, videos)

It’s used for larger apps and games (like PUBG, Call of Duty, Asphalt) that need extra data beyond the APK.

✅ Why It Exists:

Google Play automatically downloads OBB data behind the scenes, but if you’re installing manually, XAPK bundles it all together.

📥 How to Install XAPK Files:

You can’t install XAPK directly like an APK. You need a special installer.

🔧 Method 1: Using an XAPK Installer

• Download XAPK Installer or APKPure App
• Open the installer, and it will detect the XAPK
• Tap Install — it handles the APK + OBB installation

🔧 Method 2: Manual Installation (Advanced)

1. Rename .xapk to .zip and extract
2. Install the .apk file
3. Copy the OBB folder to:
   Internal Storage > Android > obb > [package_name]
4. Launch the app

📁 What Is an OBB File?

OBB (Opaque Binary Blob) is a file used by big apps/games to store additional content like maps, levels, graphics, etc.

OBBs can’t be installed on their own — they work alongside APKs.

---

📥 How to Use OBB Files:

1. Download both APK and OBB files
2. Install the APK (but don’t open it yet)
3. Extract the OBB .zip file (if needed)
4. Copy the OBB folder to:
   Internal Storage > Android > obb > [package_name]

📌 Example:
If the game package name is com.game.name, then copy the OBB folder to:
Android/obb/com.game.name/
