If you’re like most iPhone users, you probably enjoy watching videos on YouTube. But if you want to download those videos for offline viewing or sharing, you may be wondering how to do it. There are a few different ways to download YouTube videos for offline viewing or sharing on your iPhone. The easiest way is to use the YouTube app. Just open the app and search for the video you want to download. Tap the video, and then tap the three lines in the top left corner of the screen. (If the video isn’t playing automatically, tap the three lines in the top right corner of the screen.) On the next screen, tap Download Video. You can also download videos by using Safari on your iPhone. Open Safari, and type youtube in the address bar. (If it’s not already there, add www.youtube.com as a search engine.) Tap Enter, and then type in a video name or ID number (if you know it). Tap Download Video at the bottom of the page to get started. Finally, you can also download videos by using iTunes on your computer. Open iTunes, click File > Add Videos to Library… , and then select YouTube Videos from among all of your videos (.m4v) files on your computer. (You may need to select Show All Files first.) When iTunes finishes adding all of your videos, click OK . Then click Play at the top of iTunes to play each video one at a time while it downloads in its entirety onto your computer’s hard drive—you can even pause and resume downloading any time during playback! ..
