ARJ to TGZ Converter
Processing entirely on your device — large files may take a moment.
ARJ Archive and Gzipped TAR (TGZ) exist for different jobs: ARJ ruled DOS BBS archives before ZIP won — a solid-compression container whose files still surface in retro software collections. Convert TGZ exactly like TAR.GZ — unpack, repack or inspect.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 TGZ 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 TGZ?
There is a concrete reason this conversion exists: Abandoned format — no modern writers TGZ 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 TGZ 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 TGZ?
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 TGZ byte-for-byte — the conversion changes the container, never the files inside it.
