Extract Audio from Video
No video is re-encoded, so speed depends on the audio alone. WAV and FLAC are lossless and ignore bitrate.
Add files and press start. Everything runs locally in your browser; nothing is uploaded
How to Use
📖 Tool Introduction
Pull the soundtrack out of a video and save it as an audio file, entirely in your browser. Turning a meeting recording into something you can listen back to, keeping the music from a concert clip, or grabbing just the dialogue from a scene are all one click here.
Technically this only discards the picture. The audio can be copied across untouched, so it is fast: half an hour of video often finishes in seconds, and the sound is identical to the source with no loss at all.
Format depends on where it is going. MP3 plays everywhere, including car stereos, older devices and messaging apps, and 192 kbps is plenty for speech. WAV and FLAC are lossless and suit editing software or archiving, at much larger size, and bitrate does not apply to them. M4A is common in Apple ecosystems and audiobooks. OGG and Opus are more efficient per byte and suit web and real-time use.
Worth knowing: if the source audio was already lossily compressed, which most AAC in video is, then extracting to MP3 or WAV cannot bring back what was discarded. WAV preserves the data you have, it does not improve fidelity. Choose FLAC or WAV to keep every detail that survived, and MP3 when space matters more.
Processing uses a WebAssembly build of FFmpeg: about 24 MB downloads the first time and is cached after. The video is never uploaded and stays on your device.
One more thing worth knowing before you start: the extracted audio inherits whatever channels the source had. A stereo video gives a stereo file, and a video with a commentary track mixed in carries that commentary along, since nothing here separates channels.
✨ Key Features
- Six formats: MP3, WAV, FLAC, M4A, OGG, Opus
- No video re-encoding: the picture is simply dropped, so it is fast and lossless
- Four bitrates from 128 to 320 kbps, ignored for lossless formats
- Batch mode: add several videos and each is processed in turn
- Live progress showing which file is being handled
- Local processing, so the video never leaves your device
🚀 How to Use
- Drag a video into the drop area, or click to choose one
- Pick a format: MP3 for general sharing, FLAC or WAV for archiving
- Pick a bitrate, 128k for speech and 192k or above for music, then press start and watch the progress bar
- Press download when it finishes
- Bitrate is ignored for WAV and FLAC, which are lossless
⚠️ Things to Note
- Engine size: The first run downloads about 24 MB of WebAssembly engine, cached for later visits
- Lossless is not better: If the source audio was already lossy, exporting to WAV only preserves what survived. It cannot restore what was discarded
- Speed: No video is re-encoded, so time depends mostly on audio length and is usually short. A long film can still take a while because the container has to be read end to end
- Bitrate applies where it can: WAV and FLAC are lossless and ignore the setting; MP3, M4A, OGG and Opus all use it
- Privacy: The video is processed locally and never uploaded. Reloading the page clears it completely
