You usually need an Internet connection to watch YouTube videos, but you can also watch them offline using third-party apps. If you want to watch YouTube videos on your iPad, install a compatible app from the App Store to download the videos and run them offline.
Steps
Step 1. Go to the App Store page on your iPad
Step 2. Type “video downloader” into the search and download an application compatible with YouTube videos
At the moment, IT experts recommend using the "Video Downloader Lite Super" application developed by George Young, as it is free of charge and does not contain ads or pop-ups.
If you use iTunes installed on your computer to download the app to iPad, you can find the Video Downloader Lite Super app page at the following URL: https://itunes.apple.com/am/app/video-downloader-lite-super/id661041542 ? mt = 8
Step 3. When the installation is complete, launch the downloader app on your iPad
This will open the in-app browser, which will redirect you to the YouTube home page (https://www.youtube.com/).
If the site does not open after launching the application, enter the YouTube address in the address bar
Step 4. Find the video that you want to download to your iPad and click on it
Step 5. Click on the play button to start the video
Depending on the iOS version on your iPad, you will see a disc icon or a “download” option at the bottom of the window.
Step 6. Select “save” or “download” to download the video to your iPad
If nothing appears on the screen, press and hold the video player to access these options
Step 7. Enter a title for the video and click the Save button
The YouTube video will be uploaded to the Files folder. This folder is located in the downloader application folder. You can enter it at any time, with or without an Internet connection.
