The process of saving video content from YouTube to a local storage device via the internet enables offline access. For example, individuals may choose to retain a copy of a lecture for later viewing without requiring an active internet connection.
The ability to acquire and store such content provides convenience for individuals with limited internet access or those seeking to preserve content against potential removal from the source platform. Historically, third-party software and websites have facilitated this process, though the legality and ethical implications are subjects of ongoing debate.
