ARJ to TAR.GZ Converter
Processing entirely on your device — large files may take a moment.
ARJ Archive and Gzipped TAR Archive exist for different jobs: ARJ ruled DOS BBS archives before ZIP won — a solid-compression container whose files still surface in retro software collections. TAR.GZ is what open-source projects and Linux servers expect to receive.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

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.GZ format
TAR.GZ is the classic Unix distribution shape: a TAR bundle squeezed through gzip (DEFLATE-based). Every Linux package of source code, every Apache tarball, every data-science dataset arrives this way. Decompression is a pipeline — untar the gzip stream — and the format is understood everywhere Unix ideas went.
gzip compresses the whole archive as one stream, which keeps ratio decent for text-heavy trees but means reaching file #400 requires decompressing the previous 399. Modern alternatives (zstd) are faster at similar ratios, yet tar.gz remains the safest common denominator.
+ Strengths
- ✓Universally understood on Unix-like systems
- ✓Good ratio for text and source trees
- ✓Preserves Unix permissions via TAR
! Limitations
- −Single stream — no random access
- −Slower than modern zstd
- −Two-step format (tar + gzip)
Why convert ARJ to TAR.GZ?
There is a concrete reason this conversion exists: Abandoned format — no modern writers TAR.GZ sidesteps that — Universally understood on Unix-like systems If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this ARJ to TAR.GZ 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.GZ?
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 TAR.GZ byte-for-byte — the conversion changes the container, never the files inside it.
