Difference Between ZIP and RAR

File SystemSoftware & CodingData Storage

In this post, we will understand the difference between ZIP and RAR −


  • It is an archive file format.

  • It was created by Phil Katz as a standard format for lossless compression of data.

  • It is free, i.e. open standard.

  • It has many implementations and is supported in almost all places.

  • The rate of compression of ZIP is lower than that of the RAR format.

  • It offers a password based protection.

  • These files can be created with multiple programs like WinRAR, WinZIP, Freebyte Zip.

  • It uses ZIP 2.0 encryption algorithm.

  • It is a comparatively weak algorithm.

  • The filename extension can be .zip or .zipx.

  • It uses ‘DEFLATE’ compression algorithm to compress the data.

  • This is not a very efficient method.


  • It is a proprietary archive file format that is used for lossless data compression.

  • It was developed by Eugene Roshal.

  • It is not free.

  • It requires a third party tool named WinRAR archiver.

  • This WinRAR archiver helps compress or decompress files.

  • The rate of compression is better in comparison to ZIP.

  • It doesn’t offer password based protection.

  • The files are limited to one program which is WinRAR.

  • It uses AES-128 encryption.

  • This encryption technique is much more efficient.

  • The filename extensions are .rar, .rev, .r00, .r01.

  • It uses a compression algorithm that is more efficient than ‘DEFLATE’ compression method.
