7-Zip

7-Zip is a free and open-source file archiver utility. By default, 7-Zip creates 7z-format archives with a .7z file extension, but when used for creating ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip.

You can use 7-Zip on any computer, including a computer in a commercial organization. Most of the source code is under the GNU LGPL license. The unRAR code is under a mixed license: GNU LGPL + unRAR restrictions. You don’t need to register or pay for 7-Zip.
