Pull the sound out of an MP4 or WebM video — or convert an audio file — into MP3, WAV, WebM (Opus) or M4A (AAC), entirely inside your browser. Trim to the exact segment you want, pick the bitrate, and download one file. Nothing is uploaded: your media never leaves your device.
Drop a video to start
MP4, WebM, MP3, WAV and more. The audio never leaves your browser.
Drop a video and the page reads its audio track with the decoder already in your browser, then writes it back in the format you chose — MP3 for universal playback, WAV for editing, Opus in a WebM container when size matters, or AAC in an M4A container for Apple software. Pick Start and End to keep only the segment you need; the rest is discarded before encoding, not after.
| Format | Why you would pick it |
|---|---|
| MP3 | Universal playback and the widest tool support. Bitrate 64–320 kbps; 128 is the sensible default. |
| WAV | Uncompressed 16-bit PCM at 48 kHz — the format editors and DAWs want before they do their own encoding. |
| Opus (WebM) | Modern speech and music codec inside the WebM container — small files at low bitrates. |
| M4A (AAC) | The AAC codec inside an MP4 container — what iOS, macOS and most podcast platforms expect. |
The video is opened by your browser, the audio track is decoded on your device, and the encoded result is written straight back to your downloads. There is no upload, no queue on someone else's machine, and no copy left behind when you close the tab.
Because every format button corresponds to an encoder your browser actually ships, the page never promises a file it cannot produce: containers are named exactly, and formats a browser cannot encode are explained instead of silently failing.
Choose or drop one MP4 or WebM video (audio files work too), keep the format on MP3, and pick a bitrate. The page decodes the audio track with your browser's own decoder and encodes it as MP3 — the download appears when the file is ready.
MP3 plays everywhere and is the default. WAV is uncompressed 16-bit PCM — best for further editing. WebM (Opus) is the most efficient at low bitrates, and M4A (AAC) is what Apple ecosystems prefer. The container is always the one named: Opus comes as .webm, AAC as .m4a.
No, and the page says so up front: audio is resampled to 48 kHz, which is the standard rate every output format here expects. The extracted track is faithful to the source at that rate — but this is a resample, not a bit-exact copy.
Up to 10 minutes and 200 MB. Files beyond those limits are refused with an explanation instead of half-processing — these limits are safety rails, so longer media must be trimmed first.
No. Decoding and encoding happen inside your browser on your own device. There is no upload step, no server side copy, and no account.
