Open toolVideo to MP3 — Extract Audio from Video
Sometimes the video is just packaging — what you actually want is the sound: the song from a concert clip, the lecture from a recording, the voice note trapped inside a screen capture. This tool strips the picture away and saves only the audio, as MP3 (plays everywhere), WAV (lossless, for editing), M4A or OGG. It runs entirely in your browser using the FFmpeg engine compiled to WebAssembly, so the video is never uploaded — useful when the clip is private. Extraction re-encodes the audio at high quality, so what you hear in the video is what you get in the file.
Choose a file to begin — nothing is uploaded, everything happens on your device.
How to use this tool
- Choose the video whose audio you want.
- Pick the format: MP3 for everywhere, WAV for editing, M4A or OGG for smaller files.
- Click Extract audio.
- Download the audio file — the video part is discarded.
Worked example
In our test, a 3-second clip's soundtrack extracted to a roughly 13 KB MP3 — the audio stream re-encoded on its own, the video thrown away.
Frequently asked questions
What quality is the extracted MP3?
The MP3 is encoded at a high variable-bitrate setting (quality 2, roughly 190 kbps VBR) — for typical phone and camera audio that is effectively indistinguishable from the source. If the original video's audio was low quality to begin with, no extractor can add quality back; WAV keeps whatever is there bit-for-bit after decoding.
Can I extract audio from a video with no sound?
The tool will tell you if the file has no audio track — the encoder stops and you get an explanatory message instead of a silent file.
Do I have permission to extract this audio?
That is your responsibility: extract audio from videos you own or have the right to use (your recordings, your content, Creative Commons material). Copyright in the recording still belongs to its owner.
Why is WAV so much bigger than MP3?
WAV is uncompressed — roughly 10 MB per minute of stereo audio. MP3 and M4A discard sound details most listeners never hear, which is why they are about a tenth of the size. Pick WAV only when you plan to edit the audio further.
