XAPK / APKM / APKS / AAB Decompiler Online
Decompile Android bundles back to Java source code.
How It Works
Upload
Drag and drop your .xapk, .aab, .apkm or .apks file or click to browse.
Extract & Decompile
The Android bundle is interpreted and decompiled into readable sources and resources.
Browse
Explore the decompiled Java source, resources, and manifest.
What are XAPK, APKM, APKS and AAB Files?
XAPK, APKM and APKS are bundle formats used by third-party Android app stores and tools. AAB is the Android App Bundle format used by Google Play. These formats exist to distribute or publish Android applications more efficiently than a single universal APK.
- AAB — the Android App Bundle format uploaded to Google Play
- XAPK — the split APK format used by APKPure
- APKM — the split APK format used by APKMirror
- APKS — the split APK format used by SAI (Split APKs Installer)
XAPK, APKM and APKS are ZIP-like archives that typically contain:
- 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 (XAPK)
- Metadata — manifest or metadata files describing the package contents
AAB is different: it stores app modules and metadata in the publishing format used to generate device-specific APKs. AAB files are not directly installable, but they can still be decompiled.
XAPK vs APKM vs APKS 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 — APKPure's bundle format that packages split APKs together. Unlike AAB, XAPK files can be installed directly using compatible installers.
- APKM — APKMirror's bundle format. Similar to XAPK, it wraps split APKs into a single downloadable archive.
- APKS — the format used by SAI (Split APKs Installer). Bundles split APKs for backup and redistribution.
How Split APK Decompilation Works
When you upload an XAPK, APKM or APKS 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.
When you upload an AAB file, the decompiler reads the Android App Bundle modules directly and reconstructs the decompiled output from the bundle contents.
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 are XAPK, APKM, APKS and AAB files?
XAPK, APKM and APKS are split APK bundle formats used to distribute Android apps. AAB is the Android App Bundle format used by Google Play. XAPK is used by APKPure, APKM by APKMirror, and APKS by SAI, while AAB is the publishing bundle Google uses to generate optimized APKs.
What is the difference between XAPK, APKM, APKS and AAB?
XAPK, APKM and APKS are ZIP-based archives that contain split APKs from different ecosystems. AAB is the Android App Bundle publishing format used by Google Play. It stores modules and metadata rather than simply shipping installable split APKs.
How is XAPK different from APK?
A standard APK is a single package file. XAPK, APKM and APKS are bundle formats that wrap multiple APK splits (base APK plus configuration APKs for screen density, CPU architecture, and language) along with optional expansion files into one downloadable archive.
Can I decompile XAPK, APKM, APKS and AAB files online?
Yes. This tool supports XAPK, APKM, APKS and AAB decompilation. You can browse the decompiled Java source code, resources, and AndroidManifest.xml directly in your browser.
