ARJ is a classic compressed archive format created for DOS-era systems, while 7Z is a modern archive format used by 7-Zip that offers strong compression, support for large files, and advanced features such as encryption and solid archiving. Converting ARJ to 7Z means extracting the contents of an ARJ archive and repackaging them into a 7Z archive.

Why convert arj to 7z

There are several reasons to move from ARJ to 7Z:

  • Better compression in many cases, especially for mixed file collections.
  • Modern compatibility with current operating systems and archive tools.
  • Stronger security options, including AES-256 encryption in 7Z.
  • Improved handling of large archives and long file names.

Best software for arj to 7z conversion

The best choice is 7-Zip. It can open many older archive formats, including ARJ, and create 7Z archives easily. It is free, lightweight, and widely trusted.

Other useful tools include PeaZip and WinRAR, but 7-Zip is usually the most direct and reliable option for this conversion.

How to convert arj to 7z with 7-zip

  1. Install 7-Zip.
  2. Open the ARJ archive in 7-Zip File Manager.
  3. Select the files inside the archive.
  4. Choose File → Add to archive.
  5. Set the archive format to 7z.
  6. Click OK to create the new archive.

If you prefer the context menu, you can also extract the ARJ contents first, then compress them into 7Z using Right click → 7-Zip → Add to archive.

Things to keep in mind

  • ARJ is an older format, so some tools may not support it well.
  • Conversion usually means extracting and recompressing, not changing the archive format in place.
  • If the original archive is damaged, extraction may fail before conversion.
  • Check file names and folder structure after conversion to ensure everything was preserved correctly.

Recommended settings for 7z

For most users, the default 7-Zip settings are enough. If you want a good balance of speed and compression, use:

  • Compression level: Normal or Ultra
  • Compression method: LZMA2
  • Dictionary size: Default or higher for large archives

For maximum compatibility, avoid unusual options unless you specifically need them.

Summary

ARJ to 7Z conversion is best done with 7-Zip. It can open ARJ archives, extract their contents, and create a modern 7Z archive with strong compression and security features.
