Download audio from a public YouTube video
Free YouTube to MP3. This page saves the soundtrack of a public video as MP3 by default, or M4A, Opus, or WAV. We request an audio-only stream. A talk with no captions can still have audio.
How to save YouTube audio
Paste the watch URL
Same links as the transcript tool. The app requests an audio-only stream, not a muxed 1080p file.
Download the file
Format defaults to MP3. Switch to M4A, Opus, or WAV if you need them.
Do the next job
When the file is ready, jump to transcript, SRT, translation, or a chapter summary without pasting again.
Why this is not a generic “YouTube MP3” clone
Audio-only streams
We prefer adaptive audio (itag 140/251 class) so you are not downloading video pixels.
Same family as captions
After audio, one click to text, SRT, or a summary — one session, several intents.
The file is prepared after you paste
This page stays light. The audio file is built in the same app once you submit the link.
Honest failures
If YouTube only returns a signature-cipher URL we cannot decode, we say so. We do not pretend every video is downloadable.
When audio-only is the right intent
Podcast-style watch later
Save the talk for a phone player that does not need the video.
Language listening
Play the original audio while you read a translated transcript in another tab.
No captions
The video has speech but YouTube never shipped a timedtext track — audio still may work.
Limits
Only public videos we can resolve through InnerTube. Ciphered streams, DRM-ish formats, and region/age walls fail. Audio downloads cap around 3 hours. Use this for content you are allowed to keep a personal copy of. We are not a piracy mirror and we do not host a library of files.
FAQ
Is this YouTube to MP3?
Yes — MP3 is the default download. You can still pick M4A, Opus, or WAV. Use it only for videos you are allowed to keep a personal copy of.
Why did download fail?
YouTube did not give us a plain audio file, or the video is blocked on this network. Try another public video.
How large are the files?
Roughly the audio bitrate times duration (for example ~1 MB per minute at 128 kbps AAC). Downloads cap around 3 hours. We stream; we do not buffer the whole file in RAM.
Can I clip a range?
Not on the download yet. Trim exists on the transcript side. For audio, download the full stream.
Is it free?
Yes, with the same ads-around-the-tool model as the rest of YouTubeForge.
