Video to Audio
Extract audio from MP4, MOV, MKV, WEBM, AVI, MPEG, and 3GP videos.
How it works
Upload Video
Select a video file up to the site upload and duration limits.
Choose Audio
Pick MP3, M4A, WAV, FLAC, OGG, or OPUS plus quality settings.
Download
Download the extracted audio file as soon as conversion finishes.
Useful audio extraction workflows
Use the Video to Audio tool when the soundtrack matters more than the visuals, or when you need a smaller audio-only file for editing, sharing, or archiving.
Podcast clips
Turn recorded video interviews, webinars, and meetings into MP3 or M4A audio.
Editing workflows
Export WAV or FLAC when you plan to edit audio in desktop production software.
Web delivery
Use OGG or OPUS for efficient web audio and lightweight voice recordings.
About This Tool
JustConvert's Video to Audio converter extracts the first audio track from common video containers and exports it into the audio format you choose. MP3 is the safest default for phones, browsers, cars, and sharing apps. M4A is a compact modern choice, WAV is best for editing, FLAC keeps lossless quality in a smaller file, and OGG or OPUS work well for web delivery.
Conversion runs server-side with FFmpeg, the industry-standard media processing engine. The uploaded video is validated before processing, the video stream is discarded, metadata is removed from the output, and files are automatically cleaned up after the download window.

Pick the format for where the audio is going
The right format depends entirely on what you will do with the audio next, not on which sounds "best" in the abstract. For listening on a phone or sharing, MP3 is the safe universal choice. For editing in software, export WAV (uncompressed, maximum compatibility) or FLAC (lossless but smaller). For the web or voice notes, OPUS and OGG deliver good quality at tiny sizes. M4A sits between MP3 and OPUS as a compact, modern, widely supported option.
Which audio format to choose
| You'll use it for… | Best format | Why |
|---|---|---|
| Phone, car, sharing | MP3 | Plays virtually everywhere |
| Editing in audio software | WAV or FLAC | No quality loss to work from |
| Websites and voice notes | OPUS / OGG | Smallest files at good quality |
| Apple devices, compact size | M4A | Modern, efficient, well supported |
Bitrate, in plain terms
Bitrate controls how much detail a lossy format keeps. For speech — lectures, interviews, meetings — 96–128 kbps is plenty and keeps files small. For music you want to enjoy, 256–320 kbps preserves the detail. Going higher than the source can offer does not help: audio that was recorded at low quality will not improve by choosing 320 kbps, it just makes a bigger file. When in doubt, 192 kbps is a sensible all-round default. Lossless WAV and FLAC ignore bitrate entirely — they keep everything.
Frequently Asked Questions
Which video formats are supported? expand_more
You can upload MP4, MOV, M4V, MKV, WEBM, AVI, MPEG, MPG, and 3GP files up to 15 minutes long. The video must contain at least one audio track.
Which audio format should I choose? expand_more
Choose MP3 for maximum compatibility, M4A for smaller modern audio, WAV for editing, FLAC for lossless archiving, OGG for open web audio, or OPUS for efficient speech and music.
Does this reduce the video file size? expand_more
Yes. The output contains audio only, so it is usually much smaller than the original video. WAV and FLAC can still be large because they preserve more audio data.
Can I convert video to MP3? expand_more
Yes. MP3 is the default output format. Upload your video, keep MP3 selected, and click Process.
What happens if my video has no sound? expand_more
The conversion will stop and show an error because there is no audio track to extract.
