QUICK ANSWER
Is it possible to convert ARC to RAR?
No - not a direct conversion.

Only WinRAR can create .rar files, so no free conversion path exists. The practical goal - making old ARC contents accessible - is better served by extracting and repacking to ZIP or 7z, which are free to create and natively supported by modern operating systems.

Why convert ARC to RAR?

ARC (1985, SEA) and RAR (1993, Roshal) are both proprietary archive formats, but RAR creation is locked to WinRAR, ruling out any free or open conversion path. The sensible alternative is to extract the .arc contents and repack them as ZIP or .7z, both of which are free to create and far more widely readable than RAR.

How to convert ARC to RAR

PeaZip OPEN-SOURCE

Extract the .arc with PeaZip (not 7-Zip, which does not reliably support classic ARC), then repack the extracted files as .zip or .7z.

ALZip APP

Open the .arc in ALZip and extract its contents, then repack to a modern archive format such as .zip.

Quality & what to watch

  • No free tool creates genuine RAR output; any online converter claiming to produce .rar is either using a different format under the hood or is misleading.
  • ZIP opens natively on Windows, macOS, and Linux without extra software - a much better target than RAR for preserving old ARC contents.
  • 7-Zip does not reliably open classic SEA ARC files; use PeaZip or IZArc for the extraction step.

Frequently asked questions

Is ARC related to RAR?
No - ARC (1985, SEA) predates RAR (1993, Roshal) by nearly a decade and the two formats share no technology.
Why can't I convert ARC to RAR with an online tool?
No tool freely creates genuine RAR output; tools claiming to do so either re-extract and repack as a different format, or are inaccurate.
What is the safest way to preserve an old .arc file?
Extract it with PeaZip or IZArc and repack to ZIP - ZIP opens on every OS without extra software.
