Part 2. Use Online YouTube to MP3 Converters on iPhone (No App Required)

If you prefer to convert YouTube videos to MP3 online, you can try some online converters. These converters don't need you to install any apps. All you need is a working internet connection with good speed. The best part of such converters is that they are compatible with almost all operating systems, including iOS, Android, macOS, and Windows. 

1. YouTubetoMP3 Converter

YouTubetoMP3 Converter is an easy-to-use Youtube video converter that lets you convert YouTube to MP3 by using a URL. All you need is to copy and paste the link of the YouTube video you wish to convert to the download box and then choose your wanted export format (mp3). Finally, click on the "Convert" button to start the conversion process.

2. YTMP3

By using YTMP3, you can easily download and convert your wanted YouTube videos in MP4 or MP3 format. It can work seamlessly for computers, tablets, and mobile devices. There are no ads and no need for the installation of any software. All you need is a stable internet connection. But there is a shortcoming of this tool - it can only convert videos up to a length of 90 minutes. If you don't mind this, you can give it a try.

3. GO-MP3

GO-MP3 is another online converter that allows you to download YouTube videos to MP3 for free. Actually, it works similar to other online converters, and there is nothing special about it, so that we won't go into any details.

4. YTHUB.CC

YTHUB.CC works differently from the other three online converters introduced above. It doesn't require you to open another tab and copy the URL. Instead, you can directly search for your wanted videos by inputting the keywords. Another advantage of this tool is that it allows you to download YouTube playlists in MP3. If you need to download playlists, don't miss this tool.

Part 3. Convert YouTube Video to MP3 on iPhone Using an App (Without Computer)

Due to App Store restrictions, there are very few dedicated YouTube video to MP3 converter apps for iPhone, and most don't work reliably. The Documents app workaround remains one of the safest and most effective methods available.

Here's how to convert YouTube to MP3 on iPhone without computer:

Step 1. Install "Documents by Readdle" from the App Store.

Step 2. Open the app and use its built-in browser to visit an online YouTube to MP3 converter (e.g., YTMP3 or YTHUB.cc).

Step 3. Paste the YouTube video URL and choose MP3 as the format.

Step 4. Download the MP3 file and save it to the app’s storage.

Step 5. From there, you can move the file to the Files app, or open it with a music player of your choice.

This method doesn't require jailbreaking and gives you more control over the download process. However, you'll still need to be careful with ad-heavy or suspicious websites. Make sure to use only trusted online converters.
