ARJ to TAR.XZ Converter
Processing entirely on your device — large files may take a moment.
ARJ ruled DOS BBS archives before ZIP won — a solid-compression container whose files still surface in retro software collections. Produce a TAR.XZ for the smallest possible release artifact, or to match the format a build system expects.
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 TAR.XZ format
TAR.XZ is the smallest common release artifact on Linux: a tar container squeezed with LZMA2. Source distributions, distro packages and countless GitHub release assets use exactly this combination — maximum compression at an acceptable speed.
Compared to TAR.BZ2 it is both smaller and usually faster; compared to tar.gz it is considerably smaller. When a build system, mirror or repository asks for .tar.xz, producing it byte-exact is what keeps CI pipelines and maintainers happy.
+ Strengths
- ✓Highest-ratio common release format
- ✓The default for source distributions on Linux
- ✓Built-in integrity checks (CRC per block)
! Limitations
- −Decompression is memory-hungrier than gzip
- −No random access to individual files
- −Multi-threaded xz is not always compatible
Why convert ARJ to TAR.XZ?
Think of it as moving your file to the container that fits the job. Abandoned format — no modern writers TAR.XZ works differently: Highest-ratio common release format If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this ARJ to TAR.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 TAR.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.
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.
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.
