Well, in terms of just compression ability, 7-Zip is the clear winner. In addition to the built-in Windows 7 compression, I’m also going to run the same set of data on Windows 10 to see if there is any difference between the versions of Windows. I’m using a Windows 7 PC with Service Pack 1 and I installed the latest versions of each program as of the date of this post: 7-Zip 15.09 beta (64-bit), WinZip version 20 and WinRAR 圆4 5.30 beta 6. In my case, I took 1.47 GBs of videos (different formats), images (RAW and other formats), documents (PDF, Office files, etc) and music files (MP3, M4A, etc) and passed them through each compression utility with default settings.įirst, let’s start with the setup I have and the versions. I don’t like just compressing images or just compressing documents because the differences end up being very small and it’s hard to choose a clear winner.
