| Option | What it does | Best for |
|---|---|---|
| Browser MP3 extraction | Fetches HLS assets and encodes audio to MP3 locally. | Private one-off exports and short clips. |
| Time-range extraction | Downloads only overlapping segments before encoding. | Lectures, interviews, podcasts, concerts, and highlights. |
| Full MP4 export | Keeps video and audio together in an MP4 container. | When you need video, not audio-only output. |
| Desktop FFmpeg | Runs local command-line conversion. | Long streams, batch jobs, and unusual audio workflows. |
| Upload converter | Processes audio on a third-party server. | Public files that are safe to upload. |

What no-upload audio extraction means
The browser fetches the HLS manifest and media segments, then performs audio extraction with FFmpeg WebAssembly on your device. There is no upload step for the finished audio. If the optional proxy is enabled, it only routes HLS network requests needed for access.
Why MP3 extraction re-encodes audio
Unlike MP4 remuxing, MP3 output usually requires audio encoding. The extractor discards video and creates a 192 kbps stereo MP3, which is a practical format for speech, music, lectures, and offline listening on most devices.
When MP3 is the wrong output
Use MP4 when you need the video track, subtitles, or the original audio/video pairing. Use MP3 when the goal is listening offline, sharing an audio-only clip, or saving a lecture or podcast-style recording without video.

Frequently asked questions
Can I convert M3U8 to MP3 without uploading?
Yes. The browser fetches the HLS stream and FFmpeg WebAssembly creates the MP3 locally. The finished audio is not uploaded to a converter server.
What MP3 quality does the extractor use?
The tool creates a 192 kbps stereo MP3, which is a practical quality level for speech, music, lectures, and general offline listening.
Can I extract only part of an M3U8 stream as MP3?
Yes. Set start and end times before export. The browser downloads overlapping HLS segments and encodes the selected audio range.
Does MP3 extraction keep subtitles?
No. MP3 is audio-only. Use MP4 export if you need video, subtitles, or the original video/audio pairing.
Can it extract audio from DRM-protected streams?
No. It can work with normal accessible HLS streams, including AES-128 when keys are reachable, but it does not bypass DRM or license systems.
