If you want to break these limitations, you can use some third-party software or services to download YouTube videos to a PC, laptop, Mac, tablet, or mobile phone. But this has limitations, such as you can't watch the downloaded videos on the computer or laptop devices, you can't download some free movies for offline use, etc.
If you subscribed to YouTube Premium, you can download videos from YouTube directly. This is a paid service, which costs about $11.99 per month. The YouTube Premium has its own pseudo-downloading feature that allows you to save videos for offline use.
