Video to MP3 Converter — Extract Audio from Video
Extract the audio track from MP4 or WebM video and save it as MP3 or WAV — entirely in your browser, no upload.
Result
This video to MP3 converter pulls the audio track out of a video file and saves it as MP3 or WAV without any software installation and without uploading your file to a server. Drop an MP4 or WebM clip, pick the output format, press the button — and download the soundtrack a moment later, with a built-in player to check the result first.
The tool is built entirely on browser APIs. The file is read into memory, the Web Audio API's decodeAudioData unpacks the audio track straight from the video container, and the result is encoded either to MP3 through the browser's native media encoder or to a standard 16-bit WAV file written by the page itself. Because MP3 encoding streams the audio through in real time, a long recording takes about its own duration to convert — the WAV path, by contrast, is nearly instant.
Local processing means real privacy: lecture recordings, meetings, personal videos or unreleased footage never leave your computer. There is no upload limit either — the only constraint is your device's memory, not somebody's server plan. If your browser happens to lack an MP3 encoder, the tool detects that up front and automatically delivers a lossless WAV instead.
Typical uses: turning a recorded webinar into a podcast-style file, saving the music from a concert clip, extracting dialogue for transcription, or grabbing a sound effect from screen footage. If you need to trim silence or cut the extracted audio afterwards, the audio trimmer on this site picks up exactly where this tool leaves off.
