By GrabMP4 Team · Updated
If you want to save YouTube audio on your iPhone, MP3 is the most compatible format. GrabMP4 lets you extract audio at 128kbps with no downloads or apps required.
Paste the YouTube link, select MP3, and download. The file will be saved in the Files app, where you can play it offline or move it into your music or podcast workflow.
For large audio files, stay on Wi-Fi and keep Safari open until the download completes. If a download stalls, try again with the same link.
You can rename files in the Files app to keep your library organized, especially if you download multiple MP3s in a row.
