Which zip - compression program is best?

  • I always hear WinRar is so good, then WinZip is best, peazip is best... Well in the real world it's 7zip! I need something with great compression I DON'T care if it's pretty! So I took a few folders and compressed them using the best compression each program offered. Using the 64bit versions if they had them.
    7zip 64bit, WinRar 64bit, PeaZip 64bit.

    Updated compression tests with a larger folder and file sizes. 
    7zip 64 bitversion 16.04 64bit http://www.7-zip.org 
    WinRar 64 bit version 5.50 64bit https://www.win-rar.com 
    Winzip 32 bit version 22 32bit - 21 trial http://www.winzip.com
    PeaZip 64 bit version 6.5.0 64bit http://www.peazip.org 

    01-08-2018 original file size on disk 5.07 GB or 5,446,914,048 bytes, 8546 Files, 1,775 folders.
    7zip...........4.41GB.....time 03:32 minutes .7z (Ultra) (Dictionary size 32 MB 4.55GB - 2:07)
    7zip...........5.05GB.....time 00:07 minutes .tar
    7zip...........4.67GB.....time 01:22 minutes .zip
    PeaZip.......5.05GB.....time 00:07 minutes .tar
    PeaZip.......4.67GB.....time 04:31 minutes .pea
    PeaZip.......4.67GB.....time 01:07 minutes .zip
    WinRar.......4.62GB.....time 02:24 minutes .rar (Best - Dictionary size 32 MB)
    WinRar.......4.62GB.....time 01:38 minutes .rar (rar5 Best - Dictionary size 32 MB)
    WinRar.......4.67GB.....time 02:10 minutes .zip
    WinZip 22..4.66GB.....time 01:20 minutes .zip
    Windows zip...Still fails the compression because of file names.

    I did this one January 1 2017 and 7zip was clearly the winner!
    Original size 2.70 GB 28177 files in the folders.
    7zip................. 2.078GB.....time 2:02 minutes .7z
    7zip................. 2.85GB.......time 0:01 minutes .tar
    7zip................. 2.78GB.......time 1:26 minutes .zip
    PeaZip............. 2.85GB.......time 0:05 minutes .tar
    PeaZip............. 2.5GB.........time 4:44 minutes .tar.bz2
    PeaZip............. 2.78GB.......time 1:30 minutes .zip
    WinRar............ 2.78GB.......time 1:22 minutes .rar
    WinRar............ 2.78GB.......time 2:04 minutes .rar (rar5)
    WinRar............ 2.79GB.......time 4:24 minutes .zip
    WinZip21........Error log not enough memory. With 25+GB's of free memory.
    Windows zip...Can not do the compression because of file names.

    7zip is still the winner! So I know a few people don't like the GUI but it's simple, fast and gets the job done!
    And it's 100% free plus it will open any .zip, .rar, .7z, .gzip, .deb, .tar .exe... every file.

    I think the worst on the list is WinZip it installs services that run in the background which I just DON'T like and it's way over priced!

    I would rate them like this:
    1. 7zip
    2. WinRar
    3. PeaZip
    4. Windows built-in zip
    5. WinZip

    WinRar, Peazip and WinZip have made some nice jumps this year but still not as good as 7zip and 7zip is still 100% free!
