Safety notes

  • Inherits WinRAR's history of CVEs — keep extractors patched.
  • Unofficial distributions occasionally bundle malware. Verify provenance.

Common mistakes

  • For new authoring, CBZ is the friendlier choice — RAR tooling is not always available.
  • Some mobile readers can't open CBR. Ship a CBZ fallback when distributing.
