7-Zip is a freeware file compression tool. If you think Winzip or other paid file compression tools are expensive 7-Zip is a great alternative.

That covers about all the major file compression types. 7-Zip also allows you to create password protected zip files using AES-256 encryption (but also remember the length and complexity of the password you use is also important to ensure protection of encrypted data).
Although the user interface of 7-Zip is not very polished don’t underestimate the 7z file compression efficiency, 7-Zip compresses to 7z format 30-70% better than to zip format.
