YouTube Audio Downloader — Sound Only (M4A / OPUS)
Saves the audio track YouTube already stores, with no re-compression and no quality loss
Saves just the sound from a YouTube video, without the picture. YouTube already keeps the audio as a separate file, so this tool hands you that file directly. Nothing is re-compressed, so you avoid the quality loss that conversion sites introduce.

FAQ
- Can I get MP3?
- This tool does not convert. YouTube distributes M4A (AAC) and OPUS, so those are what you get. If you specifically need MP3, convert it afterwards — but converting compresses it a second time, so quality drops slightly.
- M4A or OPUS — which should I pick?
- M4A is the more compatible choice (plays on iPhone and most devices out of the box). OPUS sounds better at the same file size but some devices cannot play it. If unsure, pick M4A.
- Is this better quality than a conversion site?
- Conversion sites fetch YouTube's audio and re-compress it into MP3. Compressing already-compressed audio stacks the losses. This tool hands over the original audio file, so that step never happens.
- I want the video too.
- Use the YouTube video downloader — it saves MP4 at the quality you choose.
- Can I use the audio I download?
