As mentioned above, via MacX Video Converter Pro you can very easily download videos from various websites such as YouTube, Facebook, Vimeo, Dailymotion and others, even in 4K or 1080p. If you download music, you can convert it to, for example, AAC, MP3 and other formats. You can make great use of this function, for example, if you are traveling somewhere, but you do not have access to the Internet. You simply upload your favorite videos in advance and enjoy them later offline. And of course, you can also compress them into smaller files. The great thing is that transfers can also be applied "in reverse" - i.e. from worse quality to better. So if you have Full HD videos, for example, MacX Video Converter Pro can convert them to 4K and that's very easy.
