How to Extract Audio from Video Online

How to extract audio from video step by step
  1. Upload your video file β€” Drag and drop an MP4, MOV, AVI, or WebM file, or click browse to select from your device. No account needed.
  2. Choose output audio format β€” Pick MP3, WAV, OGG, or AAC as your target audio format. MP3 works on every device.
  3. Set quality (optional) β€” Adjust bitrate to control file size and audio quality. Higher bitrate = better quality but larger file.
  4. Extract and download β€” Click "Extract Audio" and download your audio file instantly when processing finishes.

Tip: If you're extracting music from a music video, use 256–320 kbps for the best quality. If you're extracting a speech or lecture, 128 kbps is more than enough and creates a much smaller file.

What is video to audio conversion used for?
  • Music extraction β€” Extract the soundtrack or song from music videos, concert footage, or video clips so you can listen to them as audio.
  • Podcast from video β€” Turn video podcasts, TED Talks, and lecture videos into audio files for listening on the go during commutes and workouts.
  • Voiceover & narration β€” Extract narration tracks from videos to use as voiceovers in other projects, or to transcribe the content.
  • Audiobook from video β€” Convert educational videos, course lectures, or long-form YouTube content into audio-only files for passive listening.
  • Sound effect collection β€” Extract sound effects and ambient audio from video clips for use in your own video, podcast, or music projects.
  • Interview transcription β€” Extract audio from recorded video interviews to make them easier to transcribe or to import into transcription tools.
How does video to audio extraction work?

Video files contain both video and audio tracks inside a single file container (like MP4 or MKV). Extracting audio means pulling out just the audio track and discarding the video β€” or re-encoding it to your preferred audio format.

AudioNeo uses FFmpeg WebAssembly β€” the industry-standard audio/video engine, compiled to run directly in your browser. Here's the process:

  • Local demuxing β€” Your video file is read and split (demultiplexed) into its video and audio components entirely on your device. Nothing gets uploaded to any server.
  • Audio decoding β€” The audio track is decoded from its original format (which depends on what the video used, usually AAC).
  • Re-encoding (optional) β€” If your chosen output format is different from the source audio codec, FFmpeg re-encodes it at your specified bitrate and quality settings.
  • Instant download β€” The extracted audio file is generated in your browser and ready to download immediately β€” no waiting, no uploading.

Because everything runs locally in your browser with WebAssembly, it's faster and more private than server-based converters β€” there's no upload time, and your video files never leave your device.

Frequently Asked Questions

What video formats can I extract audio from?

AudioNeo supports extracting audio from MP4, MOV, AVI, and WebM video files β€” the four most common video formats. The audio can be saved as MP3, WAV, OGG, or AAC.

Is there a file size limit?

Video files up to 50 MB are supported. Since all processing happens locally in your browser, very large files may take longer to process depending on your device's performance.

Will my video files be uploaded to a server?

No. All audio extraction happens directly in your browser using FFmpeg WebAssembly. Your video and audio files never leave your device and are never sent to any server. Your privacy is guaranteed.

What audio format should I choose?

Choose MP3 for maximum device compatibility. Choose WAV for lossless quality (large files). Choose AAC for good quality with smaller files (great for mobile). Choose OGG for open-source, high-quality compression.

Does extracting audio reduce quality?

If you extract without re-encoding (stream copy), there is zero quality loss. However, since we let you choose the output format and bitrate, some re-encoding may be involved. For best quality, choose a high bitrate like 256–320 kbps.

Can I extract audio from YouTube videos?

AudioNeo works with video files you have on your device. You need to have the video file downloaded first. We don't support downloading from YouTube or other streaming sites β€” please respect copyright laws.

Can I extract audio on my phone?

Yes! AudioNeo works on any modern mobile browser including Chrome, Safari, Firefox, and Edge on both iOS and Android. You can select videos from your phone's gallery or files app.

Is video to audio converter really free?

Yes. AudioNeo's video to audio converter is completely free with no watermarks, no hidden fees, and no daily limits. You can extract audio from as many videos as you need.
