Video to MP3 Converter
Pull the audio out of a video file and save it as MP3 — no video editor, no upload, no quality surprises.

How to use this tool
- Add the video fileThe browser opens the container and locates the audio track.
- Choose the MP3 bitrate320 kbps to preserve as much as possible, 128 kbps for speech.
- Leave channels on Keep originalMost video audio is stereo; some screen recordings are mono.
- ConvertNative containers finish quickly; MKV and AVI take longer because the FFmpeg engine loads first.
- Listen and downloadThe result card reports the decoded duration, rate and channel count.
About this tool
Extracting audio from video is one of the most common conversions there is: turning a lecture recording into something you can listen to on a walk, or saving the soundtrack from a clip you own. The video stream is simply discarded and the audio is encoded on its own.
For MP4, WebM and MOV files the browser can decode the audio natively, so the process is quick and needs no extra downloads. MKV and AVI files with less common codecs are routed through the FFmpeg engine, which the page loads on first use.
Features
- Native extraction for MP4, WebM and MOV — no engine download
- FFmpeg engine fallback for MKV, AVI and unusual codecs
- MP3 output at up to 320 kbps, or WAV for further editing
- Duration and channel count reported from the real decoded audio
- Handles hour-long recordings without a server-side size limit
- Your video is never uploaded and never modified
Frequently asked questions
Can I extract audio without re-encoding?
Only into the codec already in the file, and only with a demuxer. Since the goal is usually MP3, a decode-and-encode pass is required — which is what this tool does, at the highest bitrate you select.
Why is the extracted audio quieter than the video?
Video soundtracks are often mixed with dialogue normalisation in mind. Run the result through the volume changer or the audio compressor to bring the level up.
Which video formats work best?
MP4 with H.264 and AAC, and WebM with VP9 and Opus, both decode natively. MKV usually contains H.264/AAC too but the container needs the FFmpeg engine.
Can I extract audio from a protected streaming video?
No. Protected streams are encrypted and no browser tool can or should bypass that. Use this page on files you own.
