APK to JAR Converter
Processing entirely on your device — large files may take a moment.
Repack a JAR as ZIP to inspect classes and resources with any unzip tool. If your files are still in APK format, this page is the shortcut: APK is Android’s install package — a ZIP carrying the manifest, dex bytecode and assets.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How APK compares to JAR
| APK | JAR | |
|---|---|---|
| Layout | ZIP with manifest + DEX | ZIP with META-INF |
| Compression | DEFLATE / stored | DEFLATE entries |
| Bundling | Code, libs, assets | Classes + resources |
| Best for | App inspection | Java apps and libraries |

About the APK format
An APK is Android’s install package: a ZIP holding AndroidManifest.xml, compiled DEX bytecode, native libraries and assets. Unpacking one is the standard first step of security review, compatibility checks and asset recovery.
One honest limit: unpacking is inspection, not installation — a repacked ZIP cannot be installed back onto a phone, and the page says so.
+ Strengths
- ✓Everything an Android app ships
- ✓ZIP-based, easy to unpack
- ✓Manifest readable as XML
! Limitations
- −DEX bytecode is not human source
- −Repack cannot reinstall
About the JAR format
A JAR is a ZIP with Java manners: class files, a MANIFEST.MF, resources and optional signatures. Any tool that opens ZIPs can open it — but converting to a plain ZIP strips the “is this executable?” ambiguity and makes browsing the contents painless.
Useful for auditing dependencies, extracting embedded resources, or checking what a library actually ships before adding it to a build.
+ Strengths
- ✓Standard Java delivery format
- ✓ZIP-based, tools abound
- ✓May carry signatures and manifests
! Limitations
- −Not a installer — just a package
- −Contents are class files, not source
Why convert APK to JAR?
There is a concrete reason this conversion exists: DEX bytecode is not human source JAR sidesteps that — Standard Java delivery format If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this APK to JAR converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for APK to JAR?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are the files inside my APK archive modified?
No. Contents are unpacked in memory and repacked into JAR byte-for-byte — the conversion changes the container, never the files inside it.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the APK file.
