Using Documents and an online downloader tool
The Documents app used in the first method can be coupled with an online downloader tool to help you download music from Youtube. Here’s how:
Step 1: Launch the Youtube app, find the video you want to save music/audio from, and copy its link. (Tap on the Share button below the video and select Copy link)
Step 2: Launch the Documents app, and switch to the built-in web browser by tapping the compass icon located on the bottom.
(Step 1 & 2 are described in the first method)
Step 3: Go to http://convert2mp3.net/en/. It’s a Youtube-to-Mp3 converter site that lets you download mp3 files from Youtube video links. Just paste the video link you’ve copied before, then tap on the “Convert” button. It will then convert and generate the download link for you. The site also allows you to edit artist and name of the song. You can skip or make edits and tap Continue.
Step 4: Once the download link has been generated, tap Download. You will be able to save the mp3 to your iPhone, not to the stock Music app but to local storage of the Documents app. After the mp3 file is downloaded successfully, you can find it in the Downloads folder and play it using Documents’ music player.
Since the browser can save any files from the Web, you can also use it to download Youtube videos to your iPhone, I’ve already covered it in this article on the best video downloaders for iPhone.
If you want to create a custom ringtone from the downloaded audio, then try using GarageBand. Since iOS 11, GarageBand can import audio files from other apps so you can import your file from the Documents app to it and make a custom ringtone on your own, without using iTunes.
