jadx vs Apktool for Android
jadx 1.5.6 (July 2026) decompiles Android DEX bytecode to Java source, while Apktool 3.0.3 (July 2026) decodes and rebuilds an APK's resources and manifest.
jadx and Apktool solve different Android jobs:
- jadx (skylot/jadx) — Dex to Java decompiler (Apache-2.0). Latest release checked 2026-10-17 (UTC): v1.5.6.
- Apktool (iBotPeaches/Apktool) — decode resources to near-original form and rebuild after modifications; smali-oriented workflows (Apache-2.0). Latest release checked: v3.0.3. Apktool's README states it is NOT intended for piracy and other non-legal uses.
Use jadx to read Java-like source from DEX; use Apktool to inspect/edit resources and smali with rebuild support. Many authorized analyses use both.
Comparison table
| jadx | Apktool | |
|---|---|---|
| Primary job | Decompile DEX → Java-like source | Decode/rebuild APK resources + smali workflow |
| License | Apache-2.0 | Apache-2.0 |
| Latest tag checked | v1.5.6 (2026-07-10 UTC) | v3.0.3 |
| Typical output | Java sources / GUI tree | Decoded project (apktool d / b style workflows — see official wiki) |
| Piracy stance | General RE ethics apply | README: not for piracy / non-legal uses |
| Site / docs | GitHub skylot/jadx | https://apktool.org |
Typical authorized workflow (high level)
- Confirm you may analyze the APK (your build, written permission, malware lab sample you are allowed to hold, etc.).
- Open in jadx to understand Java/Kotlin logic.
- Use Apktool when you need decoded XML/resources or a rebuildable project structure.
- Do not redistribute modified proprietary apps or bypass licensing/DRM.
Exact CLI flags change across versions — follow apktool.org wiki and jadx release notes rather than memorizing flags from third-party blogs.

FAQ
Which one produces Java source?
jadx is the Dex-to-Java decompiler. Apktool focuses on resources/smali/rebuild.
Can Apktool “crack” paid apps?
No legitimate guide does that. Apktool's authors reject piracy uses; BinBench does too.
Is jadx the same JAR REA pins?
REA's Android lane pins jadx-headless-mcp 0.7.1 for its bridge — a specific headless artifact, not necessarily identical to every jadx GUI release. See RepoRead's Android article if you use REA; this BinBench page compares the standalone tools.
Where do I download?
Only upstream GitHub Releases / apktool.org mirrors linked by the project.
