Free · No watermark · No sign-in
Actually processed locally
The browser File API reads your video and WebAssembly processes its audio on this device. It is never sent to our servers.
Export the format you actually need
Use MP3 for sharing, WAV for editing and archives, M4A for Apple and podcast workflows, or copy the source track without re-encoding.
Trim before you extract
Export only the interview, lesson, or screen-recording segment you need without opening another editor.

Why extract audio from a video?
A smaller, editable audio file makes existing video useful for podcasts, transcripts, lessons, and new edits.
Transcription and study
Pull sound from lectures, meetings, and lessons for a smaller transcription or offline-listening file.
Reuse a voice-over
Keep narration, commentary, or dialogue while replacing the visuals or building a new edit.
Music and sound clips
Save a soundtrack or sound effect from video you own or may use, or export only the section you need.
Extract audio from MP4, MOV, WebM, MKV, and more
Process common camera, phone, screen-recording, and web video formats directly in the browser. Final compatibility depends on the audio codec inside the file.
No software to install. Files can be up to 500 MB; smaller videos work best on phones and low-memory devices.

Extract audio from video on any device
Use a modern browser to convert the file on the device you already have. Speed depends mainly on video length, output format, and available memory.
iPhone and iPad
Choose a MOV or MP4 from Files or your photo library. For long videos, use Original or trim first to reduce memory use.
Android phones and tablets
Open Chrome and choose a recorded or downloaded video. MP3 is easy to share; M4A balances quality and size.
Windows, Mac, and Linux
Handle most common formats in a desktop browser without installing a traditional video editor.
Get the best audio quality from your video
Extraction cannot restore detail missing from the source, but the right output choice prevents unnecessary quality loss.
Choose Original to preserve the source
It copies the audio stream without re-encoding, so it is usually fastest and adds no new compression loss.
Choose WAV for editing or archiving
WAV is uncompressed and ready for an audio editor. The file is larger, but later edits avoid another lossy encode.
Choose MP3 or M4A for everyday use
128 kbps is often enough for speech, 192 kbps suits general use, and 320 kbps is useful for music.
Start with the best source available
If the video is distorted, heavily compressed, or very quiet, extraction cannot recreate missing sound detail.
Frequently asked questions
How do I extract audio from a video online?
Choose or drop a video, set the time range and output format, then select Extract audio. Preview the result and download it when processing finishes.
Can I convert MP4 to MP3 for free?
Yes. Choose an MP4, select MP3 and a 128, 192, or 320 kbps bitrate, then convert it for free with no sign-in or watermark.
Is my video really never uploaded?
Yes. Reading, trimming, transcoding, and output creation all happen in this browser. Only the processing engine code is downloaded from a CDN on first use.
Which video formats are supported?
MP4, MOV, M4V, WebM, MKV, AVI, and common MPEG files are accepted. Final support depends on whether FFmpeg WASM can decode the audio codec inside the video.
How is Original different from MP3?
Original copies the existing audio bytes, so it is fast and avoids generation loss. MP3 re-encodes the audio but plays on more devices.
Can I extract only part of the audio?
Yes. After loading the video, drag the range handles to set a start and end time. Only the selected section is exported.
Does extracting audio reduce sound quality?
Original does not re-encode. MP3 and M4A are encoded at your chosen bitrate. WAV is uncompressed, but it cannot restore detail already missing from the video.
Can I extract audio on iPhone or Android?
Yes. Modern Safari and Chrome can process files locally. Long videos use more memory, so smaller or pre-trimmed files work best on phones.
Can I paste a YouTube link?
No. This tool reads video files already on your device and does not download content from online platforms. Only process video you own or may use.
Why can large files fail on phones?
The browser must hold the source and output in memory. Low-memory devices may run out before the 500 MB page limit; trim the source or use a computer.
