What is ARJ?

ARJ is a legacy DOS/Windows compression format popular in the 1990s, offering good compression ratios for its time.

What is XAR?

XAR files are built around lossless compression. Designed for macos package installers, browser extension packaging, they use the application/x-xar MIME type and typically range from varies by content.

When Should You Use ARJ vs XAR?

Use ARJ When...

Reach for ARJ when your priority is legacy archives, dos-era file distribution — its efficient compression makes sharing fast and storage minimal.

Use XAR When...

Reach for XAR when your priority is macos package installers, browser extension packaging — its uncompromising quality ensures every detail is preserved.

ARJ vs XAR: Key Differences

•ARJ and XAR diverge on compression: lossy compression for the source, lossless compression for the target.
•Moving from ARJ (lossless) to XAR (lossless) means the output file will be larger — but every bit of the original is preserved.
•How transparency is handled: XAR supports transparency, so alpha information is preserved during conversion.
•XAR files tend to be differently sized than ARJ
•ARJ is optimized for legacy archives, dos-era file distribution while XAR is designed for macos package installers, browser extension packaging — choose based on your specific workflow needs

Troubleshooting ARJ to XAR Conversion

!The converted XAR archive is smaller than expected → some files may have been skipped; verify the file count matches the source
!File permissions lost in the converted XAR → not all archive formats preserve Unix permissions and ownership metadata
!The XAR archive extracts to a different folder structure → verify that the source archive stored paths relatively, not absolutely
!Encrypted ARJ files converted to XAR lost their encryption → encryption must be re-applied after format conversion
