ARJ to APK Converter
Processing entirely on your device — large files may take a moment.
Repack an APK as ZIP to inspect its manifest and assets (not for reinstalling). If your files are still in ARJ format, this page is the shortcut: ARJ ruled DOS BBS archives before ZIP won — a solid-compression container whose files still surface in retro software collections.
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.

About the ARJ format
ARJ was the power-user archiver of the DOS era — solid compression (later files reference earlier ones for better ratios), multi-volume spanning and self-extracting executables, years before ZIP caught up. Software collections from the early 1990s are full of .arj volumes.
7-Zip's decoder still reads ARJ, so those collections remain extractable: unpack in the browser and repackage into ZIP for anything modern.

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

Frequently asked questions
Is this ARJ to APK 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 ARJ to APK?
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.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
Are the files inside my ARJ archive modified?
No. Contents are unpacked in memory and repacked into APK byte-for-byte — the conversion changes the container, never the files inside it.
