Best Freeware File Compression Software For Windows

File compression or file archiving is nothing new for the computing world. In fact its pretty much de-facto for users who regularly downloads files or share files. The concept of packing multiple files into a compressed archive before sending it to someone was very important in the earlier days of the Internet with very less bandwidth. Although the Internet is much faster now with lots of bandwidth, the concept of file compressing is still going great. People still compress files (multiple files) into a single file before sending them over the Internet. One of the advantages of using file compression is it reduces the chances of forgetting to attach an important file. It’s also very frustrating for the person who is receiving the file. Instead of downloading multiple files one after another, he/she just needs to download a single archive. This also bypasses (if the compressed file is password protected) the compressed files from the prying eyes of various email or cloud storage services.

Natively, almost all operating systems can open ZIP files, the most popular file compression format. Although the built-in compression feature on Windows operating system leaves a lot of space for improvement. The ZIP file format is good enough for most users but the world has moved on from using ZIP format to compress files. Many different open-source and proprietary formats like RAR, ARC, TAR, 7Z, etc. are in use now. All these different archive formats has made the need for a dedicated file compression app on Windows a necessity. Here’s a quick look at the five best free file compression software for Windows.

Here’s we are including only freeware software for Windows. Naturally, we excluded popular file compression apps like WinRAR, WinZIP and others that are shareware and not free.
