WinRAR automatically recognizes and selects the best compression method. WinRAR supports all popular compression formats (RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z and 7-Zip).This will save you disc space, transmission costs AND valuable working time as well. By consistently creating smaller archives, WinRAR is often faster than the competition. WinRAR puts you ahead of the crowd when it comes to compression. If you want an intuitive GUI client for your compression / decompression needs we suggest you try The Unarchiver or Keka. Note: WinRAR for macOS is a command-line only application.
