9 Free File Compression - WinZip And WinRAR Alternatives With High Compression Ratio

Personally, I find both 7-Zip and IZArc reliable and good. However, I am somewhat biased towards 7-Zip because I’ve been using 7-Zip for quite some time, IZArc comes with more features such as reading ISO files, but the biggest issue I have with them is their sneaky way of installing third party software.

1. 7-Zip


7-Zip uses its own 7z archive format, but can read and write several other archive formats. The program can be used from a command-line interface, graphical user interface, or with a window-based shell integration. 7-Zip began in 1999 and was developed by Igor Pavlov. The cross-platform version of the command-line utility, p7zip, is also available.

  • For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
  • Strong AES-256 encryption in 7z and ZIP formats

After the trial period expires, the program will start to nag you to buy it every time you open up a zip, rar, etc. You can still use the software, but with the nag screen.
