Extract Audio from Video (Video to MP3, M4A, WAV)
Extract audio from video files and save the sound as MP3, M4A, WAV, FLAC or Opus. Choose M4A and the AAC soundtrack found in most phone and camera videos is copied bit for bit, with no quality loss at all. Any video format works, one file or a whole batch, and the extraction runs on your own device: nothing is uploaded and there is no size limit.

How to extract audio from a video
Step 1: Drop one or more videos on the box above: MP4, MOV, MKV, WebM, AVI and other formats all work.
Step 2: Pick a format under Save as. MP3 plays everywhere; M4A keeps the original quality; WAV is best for editing.
Step 3: For MP3 or Opus, choose a Bitrate (192 kbps is the default). Sample rate and channels are under Advanced settings.
Step 4: Press Extract and download the audio files, one by one or as a ZIP.
Good to know
Settings explained
- Save as
- M4A copies the original AAC audio without re-encoding when possible.
Formats
Batch-friendly: add many files and they are processed one after another — if one fails, the rest still finish.
How it runs
- Hardware video engine
- Video is decoded and encoded by your device’s media hardware through WebCodecs — usually several times faster than real time.
- FFmpeg (when needed)
- Older formats and a few filters use FFmpeg compiled to WebAssembly. It downloads once (about 31 MB) the first time it is needed and is cached for offline use.
MP3, M4A or WAV: which format should you save as?
For the widest compatibility choose MP3, for zero quality loss from a phone video choose M4A, and for editing or transcription choose WAV. Converting one specific pair? The MP4 to MP3 converter is preset for MP3, and there are presets for MP4 to WAV, MOV to MP3 and MKV to MP3.
| Format | Quality | Size per minute (stereo) | Plays on | Choose it for |
|---|---|---|---|---|
| MP3 | Lossy; 192 kbps sounds transparent for most sources | 1.44 MB at 192 kbps, 2.4 MB at 320 kbps | Everything: phones, cars, players, editors | Music players, sharing, ringtones |
| M4A (AAC) | Identical to the original when the video has AAC sound | Same as the soundtrack inside the video | iPhone, Mac, Android, most players | Keeping the exact original sound |
| WAV | Lossless 16-bit PCM | 10.6 MB at 44.1 kHz, 11.5 MB at 48 kHz | Every editor and DAW | Editing, Premiere, Audacity, transcription services |
| FLAC | Lossless, compressed | Usually well under WAV | Most players and editors; not every phone app | Archiving without wasting space |
| Opus | Lossy, efficient at low bitrates | 0.48 MB at 64 kbps | Browsers, Android, WhatsApp-style voice apps | Speech at small sizes |
Can you extract audio from a video without losing quality?
Yes. Most MP4 and MOV videos from phones, cameras, screen recorders and messaging apps carry their sound as AAC. Saving as M4A copies that AAC track into an audio file untouched, so the result is bit-for-bit the original soundtrack and the extraction takes seconds. The result card says “Lossless copy of the original” when that happened.
If the video’s sound is something else (Opus in a WebM, AC-3 in an MKV) or you change the sample rate or channels, the audio is decoded and encoded again. WAV and FLAC are then the lossless targets: they keep exactly what the decoder produced. MP3 is always a fresh encode, so pick 192 kbps or more for music.
Video to MP3 settings explained
The defaults suit almost every video: 192 kbps MP3, original sample rate, original channels. Change them only for a reason.
| Setting | Options | When to change it |
|---|---|---|
| Bitrate (MP3, Opus) | 64, 96, 128, 192, 256 or 320 kbps | 64–96 kbps for speech to save space; 256–320 kbps only for high-quality music sources |
| Sample rate | Original, 22.05, 32, 44.1 or 48 kHz | 44.1 kHz for CD-style music projects, 48 kHz to match video editors |
| Channels | Original, stereo or mono | Mono for voice recordings; it halves WAV size |
Extract audio from a video on iPhone, Android, Windows or Mac
The extractor works in Safari, Chrome, Edge and Firefox on every system, with the same options. Only the place you pick files from changes.
iPhone and iPad
The Photos app cannot save just the sound. In Safari here, tap the drop zone, choose Photo Library, then save the MP3 or M4A to Files. M4A files play in the Files app and can be shared to any audio app.
Android
In Chrome, pick videos from your gallery or downloads. Audio files land in Downloads, where music players and file managers find them.
Windows
There is no one-click option built into Windows. Drag the videos from File Explorer into Chrome or Edge; long recordings work because the file is read from disk in chunks.
Mac
QuickTime Player can Export As → Audio Only to M4A for one file. This page also does MP3, WAV and FLAC, MKV and WebM sources, and batches.
Why save audio from video here
- No upload, no cap. Lectures, concerts and meeting recordings stay on your device, however large.
- Lossless when possible. AAC soundtracks are copied, not re-encoded, when you save as M4A.
- Batch-friendly. Drop a folder of clips and get one audio file per video, named after it.
- Any video format. Older formats such as AVI, WMV or FLV load the FFmpeg engine once and work the same way.
Tips & troubleshooting
Only need part of the sound? Shorten the video with the video trimmer first, or cut the audio afterwards with the MP3 cutter.
Want the words, not the sound? Video to text transcribes speech on your device.
Making a ringtone from a clip? Extract the audio, then shape it with the ringtone maker.
Quiet recording? Clean it with Remove background noise before or after extracting.
Converting the extracted file again later? Keep a WAV or M4A master and make MP3s from that, not from another MP3.
Extract Audio from Video FAQ
How can I convert video to MP3 for free?
Drop the video here, leave Save as on MP3 at 192 kbps and press Extract. It is free, has no daily limit and adds nothing to the file. For MP4 files specifically, the MP4 to MP3 page has the same converter preset for MP3.
Which audio format should I save as: MP3, M4A or WAV?
MP3 if the file has to play everywhere, M4A if the video came from a phone or camera and you want the exact original sound, and WAV if it is going into an editor or a transcription service. WAV files are seven to eight times larger than a 192 kbps MP3.
Can I extract audio from a video on my phone?
Yes. Open this page in Safari or Chrome, pick the video from your photo library and press Extract. The audio file is saved to Files on iPhone or Downloads on Android. Very long 4K videos are quicker on a computer.
How do I extract audio from a WhatsApp video?
Save the video from the chat to your gallery or files first, then drop it here. WhatsApp videos are MP4 files with AAC sound, so choosing M4A copies the audio without any quality loss.
Can I extract audio from a YouTube link?
No. This tool works on video files on your device and never fetches anything from a link. If you have the right to a video, save the file first, then extract its sound here.
What happens with videos that have several audio tracks?
The main (first) audio track is extracted. Multi-language MKV files therefore give you the default language. Surround tracks are usually mixed down to stereo; set Channels to Stereo under Advanced settings to be sure.
Is there a file size limit?
There is no upload limit because there is no upload. Videos are read in chunks straight from disk, so multi-gigabyte files work on desktop computers; phones are limited by their memory. There are no daily caps and no watermark.
