APK vs XAPK vs APKS: What’s the Difference? (2025 Beginner’s Guide)

If you download MOD APKs or custom apps online, you’ve probably seen file types like .apk, .xapk, or .apks.

But what do they mean? Can you install them like normal APKs?
This 2025 guide breaks it down clearly for beginners.

1. What Is an APK File?

APK stands for Android Package Kit.

It’s the standard file format for installing apps on Android.

Key points:

• Used for most apps
• Can be installed directly
• One file contains all app data
• Common size: 5 MB – 200 MB

You can install APKs by enabling “Install Unknown Apps” in Android settings.

2. What Is a XAPK File?

XAPK is a compressed package containing:

• APK file
• OBB file (extra game data)

It’s used when the app size is large (typically > 200 MB) and includes additional assets.

Key points:

• Must be extracted or installed using a XAPK installer
• Used by large games (e.g., PUBG, Free Fire MODs)
• Can’t be installed directly like APK

Tools to install:

• XAPK Installer
• ZArchiver + Manual copy of OBB file

3. What Is an APKS File?

APKS is a split APK format used by Google Play to optimize app delivery.

An .apks file contains:

• Base APK
• Config APKs (for screen size, CPU, language, etc.)

Key points:

• Not installable directly
• Requires Split APKs Installer (SAI)
• Smaller file sizes, better performance
• Common for modern apps and MODs

Install with:

• Split APKs Installer (SAI)
• APKMirror Installer

How to Know Which Type You’ve Downloaded
