Notes:

  1. ^  Application is only for decompression.
  2. ^  GNU tar calls the external programs gzip and bzip2 to perform compression; these external programs usually come with systems that contain GNU tar.
  3. ^  Allows adding a variable amount of redundancy for much better error recovery. See also RAR (file format).
  4. ^  BitZipper uses various methods to extract data from damaged files.
  5. ^  Extracting/adding file and/or directory names into archive in either UTF-7, UTF-8 or UTF-16/UCS-2 encoding to support single file/directory name which contains characters from different languages. More recent versions of the zip file format have support for Unicode filenames.
  6. ^  In WinRAR 3.60, when opening 7-Zip archives which contains Unicode file/directory names, they will not be displayed correctly. There will be no problem extracting them, however.
  7. ^  Does support Unicode names, but not under the default (initial) option settings: the user must tick "Use OEM conversion for filenames" under "General" on the "Miscellaneous" tab in the Configuration dialog to enable Unicode name support. Full support for Unicode files names by default is supported only for 7-Zip and RAR archive formats.
  8. ^  Commandline batch compression is available only for ZIP and ALZ formats.
  9. ^  UTF-8 support was completed in release 2.5. On Unix system the support is full, while on Windows system, due to limitation of the Windows shell environment, double-character encoded characters cannot currently be displayed in filenames of archived objects, and those chars are replaced by jolly character. Optionally extended characters can be set to be always replaced by jolly "?" character to avoid possible issues between archive's and system's character encodings.[3].
  10. ^  Commandline batch compression and expansion requires free add-on software downloaded from the WinZip website.
  11. ^  Peazip supports file encryption and file name encryption, although only in certain types of archives, including its own Pea format, 7-zip, zip and Arc.

ZIP TAR AFA UHA GZ BZ/BZ2 7z RAR LHA ACE SIT SITX ARJ KGB DAR ARC CAB ALZ ISO/CD Image

Notes:

  1. ^  Used to, but no longer does, due to technical and legal issues. More info
  2. ^  GNU tar calls external programs[1] (like compress, gzip or bzip2 or any other programs working with abstract streams and supporting the "-d" option) to perform (un)compression, and allowing you to implement your own filters[2]. These external programs may be shipped with your Operating System.
  3. ^  GNU tar let you to implement your own filters[3], allowing you to use others compression program (p7zip, ...) and others filters (GPG, ...).
  4. ^  Starting from version 11.
  5. ^  Requires external program. More info
  6. ^  ALZip also reads: alz, ace, arc, arj, b64, bh, bhx, bin (hex files), bin (CD images), bz2, cab, ear, enc, gz, ha, ice, iso, jar, lcd, lha, lzh, mim, pak, rar, tar, tgz, uue, uu, war, xxe, z, zip, zoo, 7z, and 001
  7. ^  Archive Utility itself is unable to open ISO files, but Disk Utility, which also comes with Mac OS X, is able to mount them as virtual disks.
  8. ^  As in most applications of this type, latest modification to ZIP standards (i.e. new PPMd compression modes) may be not immediately supported as they are introduced by WinZip or PKZip teams. Support to ZIP standards is one of the widest available in free applications (i.e. full support to Deflate64 compression, AE encryption, decryption of PKZip's AES etc...)
  9. ^  Requires external programs.[4]
  10. ^  Requires external program.[5]
  11. ^  Only partial support for reading proprietary SITX format. [6]

Compression comparison

File compressor and archivers vary in terms of compression ratio and the time it takes to process data. Various benchmark sites attempt to evaluate the differences.

Open benchmarks

Benchmarks that are open and transparent:

Closed benchmarks

Benchmarks that use secret test data and arbitrary selection of compression software:

Uncommon archive format support

Some archivers support file extraction from .msi and .iso formats as well. These include WinRAR, PowerArchiver, ALZip, IZArc, and 7-Zip.

PeaZip has full support for various LPAQ and PAQ formats, QUAD and BALZ (highly effcient ROLZ based compressors), FreeArc format, and for its native PEA format.

7-Zip, as of version 4.65, can read certain rare methods of common formats: for example, multivolume Cabinet (.cab) files, and old ZIP "Shrink" compression method 1,[4] a Lempel–Ziv–Welch compression that has not been in common since PKZIP 0.9.[citation needed] It can also read these formats not listed above:

7-Zip beta, as of version 9.07, reads and writes .xz files, which are LZMA2-compressed. 9.07 can also extract from:
