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.
