ARJ to XZ Converter
Processing entirely on your device — large files may take a moment.
Unpack XZ into ZIP/TAR for tools that cannot read LZMA2. 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.
+Strengths
- ✓Solid compression was ahead of its time
- ✓Multi-volume and SFX support
- ✓Still readable via 7-Zip
!Limitations
- −Abandoned format — no modern writers
- −Windows-125x filenames can mojibake
- −DOS-era paths (8.3 remnants)
About the XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux
Why convert ARJ to XZ?
Converting makes sense where the strengths of XZ meet what ARJ cannot give you. Highest common ratio Meanwhile Abandoned format — no modern writers One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this ARJ to XZ 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 XZ?
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.
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 ARJ file.
Are the files inside my ARJ archive modified?
No. Contents are unpacked in memory and repacked into XZ byte-for-byte — the conversion changes the container, never the files inside it.
