Extract Audio from Video — Free & Private

Most converters make you upload the video first. This one pulls the audio out — as MP3, FLAC, OGG, M4A, or WAV — the moment you pick the file. No upload, no account, nothing leaves your device.

  • No artificial size limits

Which audio format should I choose?

  • MP3 — the universal choice. Small files (roughly 3–8 MB per minute), plays everywhere. High preset uses ~245 kbps VBR; Balanced uses ~165 kbps. Good for music, podcasts, and speech.
  • FLAC — lossless and compressed. Same quality as the original, about half the size of WAV. Best for archiving or mastering. Plays in VLC, foobar2000, and most modern players.
  • OGG (Vorbis) — open-format, royalty-free. Similar quality to MP3 at lower bitrates. Good for games, open-source projects, and anywhere MP3 licensing is a concern.
  • M4A (AAC) — Apple's format. High preset gives 256 kbps. Native on iPhone, iPad, Mac, and iTunes. Slightly better quality than MP3 at the same file size.
  • WAV — uncompressed, bit-perfect. ~10 MB per minute of stereo audio. Choose this when you plan to edit the audio further in a DAW — editing compressed audio accumulates quality loss.

Extract audio from a specific segment

Use the Trim control in the converter to set a start and end time before extracting. Only that portion is processed, so the output file contains exactly the audio you want — no need to trim it down afterwards.

Supported input formats

Any video format your browser can decode:

  • MP4, MOV — the most common formats, including iPhone recordings
  • MKV — multi-track Matroska files (outputs the first audio track)
  • AVI — older Windows video
  • WebM — web video with Opus audio
  • WMV, FLV, M4V, 3GP, and more

How it works

Extraction runs locally in your browser, using a WebAssembly build of ffmpeg. Nothing is uploaded — your video file is read straight from your device, the audio stream is pulled out and re-encoded to the format you choose, and the output is saved to your downloads folder. Your device does the actual extracting; we just supply the code that runs it. Skipping the upload is what makes this fast, especially for large files — and what keeps everything 100% private, as it should be.

Frequently asked questions

Which format is lossless?
FLAC and WAV are both lossless — no quality is lost from the original. FLAC is typically 40–60% smaller than WAV, which makes it the better choice for archiving. WAV is the fallback if your audio editor doesn't support FLAC.
Will extracting audio change the quality?
WAV and FLAC copy the audio data without re-encoding, so nothing is lost. MP3, OGG, and M4A do re-encode the audio, but at the High preset the loss is inaudible for most music and speech — you'd need a trained ear and a direct comparison to notice.
Can I extract audio from just part of the video?
Yes. Use the Trim control to set a start and end time before extracting. Only that segment is processed, so the output file contains exactly the part you want — no need to cut it down afterwards in another app.
My video has multiple audio tracks — which one gets extracted?
The first audio track is extracted, which for MKV files with multiple language tracks is typically the default language. If you need a specific track instead, multi-track selection is on our roadmap — for now, re-mux the file to reorder tracks first.
Can I extract audio from large video files?
Yes. There's no file size limit because nothing is uploaded to a server — the only real constraint is your own device's available memory, and that's rarely a problem even for hour-long recordings or multi-gigabyte files, since audio-only encoding is light work.
