XAPK Decompiler Online
Decompile Android XAPK split APK bundles back to Java source code.
How It Works
Upload
Drag and drop your .xapk file or click to browse.
Extract & Decompile
The XAPK is extracted and the base APK is decompiled with JADX.

What is an XAPK File?
XAPK is a split APK bundle format commonly used by third-party Android app stores like APKPure. It was created to address the limitations of distributing large Android applications as a single APK file.
An XAPK archive typically contains:
- Base APK — the core application package with compiled code and essential resources
- Split APKs — additional packages for specific screen densities, CPU architectures (ARM, x86), or languages
- OBB files — expansion data files for apps that exceed the APK size limit
- manifest.json — metadata describing the package contents and installation requirements
XAPK vs APK vs AAB
Android uses several package formats, each serving a different purpose:
- APK — the original single-file format. Contains everything needed to install an app on any compatible device, which means it includes resources for all screen densities and architectures, making it larger than necessary for any specific device.
- AAB (Android App Bundle) — Google's modern distribution format used on the Play Store. Google generates optimized APKs for each device configuration. AAB files cannot be installed directly on devices.
- XAPK — a third-party bundle format that packages split APKs together. Unlike AAB, XAPK files can be installed directly using compatible installers. They provide the size benefits of split APKs while remaining installable outside the Play Store.
How XAPK Decompilation Works
When you upload an XAPK file, the decompiler first extracts the archive to access the individual APK files inside. It then identifies the base APK — the one containing the main application code — and decompiles it using JADX.
The decompilation process converts Dalvik bytecode (DEX files) back into readable Java source code, decodes binary XML resources, and extracts all bundled assets. The result is a browsable file tree that closely mirrors the original project structure.
Frequently Asked Questions
What is an XAPK file?
An XAPK file is a split APK bundle format used to distribute Android apps. It contains the base APK along with additional split APKs and OBB data files, packaged together in a single archive. XAPK is commonly used by third-party app stores like APKPure.
How is XAPK different from APK?
A standard APK is a single package file. XAPK is a bundle format that wraps multiple APK splits (base APK plus configuration APKs for screen density, CPU architecture, and language) along with optional OBB expansion files into one downloadable archive.
Can I decompile XAPK files online?
Yes. This tool extracts the XAPK bundle, identifies the base APK, and decompiles it using JADX. You can browse the decompiled Java source code, resources, and AndroidManifest.xml directly in your browser.
