If you are looking for a free online video downloader which supports downloading any video online from any site using URL, you definitely can not miss VidPaw Online Video Downloader. VidPaw is able to convert videos from YouTube, Vimeo, Instagram, Facebook and so on to many formats like MP4 in high quality. No software is needed and easy to use on both Windows and Mac.
However, even free, you can grab 4K video from YouTube with no problem. A 575.4MB file took over 10.5 minutes—no surprise with the speed restriction, but still agonizingly painful. There's an option to convert the file to MKV, AVI, or WMV as you download it. If you want a playlist, you can do them in a batch, but in my test TubeGet would only allow a max of 1080p HD even on the 8K video playlist.
That said, with Android it is possible to install apps without going through Google. The latest is InsTube – Free Video and Music Downloader just for Android—you can only get it at InsTube's site. You download the APK (Android application package) file to sideload on an Android device. Find it in your device's downloads and click it to install. (You may have to go into your security settings and enable "Unknown sources.") There is a similar side-load app from YTD.
