Downloading YouTube videos directly to your iPhone is against YouTube's terms of service and violates copyright laws. However, YouTube Premium subscribers have access to the offline viewing feature, which allows them to download videos for offline playback on mobile devices, including iPhones.
If you're a YouTube Premium subscriber, you can download YouTube videos for offline viewing using the YouTube app for iOS. Here's how to do it:
1. **Open the YouTube App**: Launch the YouTube app on your iPhone.
2. **Find the Video You Want to Download**: Navigate to the video you want to download for offline viewing.
3. **Tap on the Download Button**: Below the video player, you'll see a "Download" button. Tap on this button to initiate the download.
4. **Select Video Quality**: After tapping the download button, you'll be prompted to select the video quality for the download. Choose the video quality you prefer (higher quality videos will take up more storage space).
5. **Wait for Download to Complete**: Once you've selected the video quality, the video will begin downloading. Wait for the download to complete.
6. **Access Downloaded Videos**: To access your downloaded videos, go to the Library tab in the YouTube app and select the "Downloads" section. Here, you'll find a list of all the videos you've downloaded for offline viewing.
Please note that downloading YouTube videos using third-party apps or websites is against YouTube's terms of service and may be illegal. Additionally, these methods may pose security risks to your device and personal information. It's important to respect copyright laws and the rights of content creators when using YouTube.
