There is no shortage of ways to download YouTube videos on the Internet. Special websites, browser plug-ins or trivial screencast recording are all good in their own way. Now YouTube is finally offering a simpler solution for computer users: a download button.
According to a source, it's currently available as an experimental feature for Premium subscribers. This is no surprise, since YouTube already offers video downloads for Premium subscribers from mobile devices.
Once this feature is enabled, you'll see a download button next to the share option below the video or next to the three-point menu when you view it. You can choose video resolutions from 144p to 1080p - unfortunately, no 4K (yet). There is currently no limit on the size of the downloaded file, other than the storage available on your device, of course.
If you want to try the new feature, go to youtube.com/new and check out the Labs page as an authorized Premium subscriber. You may see something like this:
After you click on the "Try" button, a new "Download" button will appear in the YouTube interface.
Then all you have to do is click it and the video will be saved to your computer. Location of saving - the cache of your browser. Downloaded videos can be viewed at youtube.com/feed/downloads. The feature works on Windows, macOS and Chrome OS.
