Extract Audio from Video Online Free — PrivaTools

TL;DR: Upload a video file and download just the audio track — pick MP3, WAV, AAC, or FLAC.

Extract audio from video online for free — pull the audio track from any MP4, MOV, WebM, or AVI file and save as MP3, WAV, or OGG. No quality loss.

Extract Audio from Video runs on the same privacy-first stack as every PrivaTools utility: files enter an isolated Docker container, are processed in temporary memory, and are unlinked the moment your download begins. No account, no watermark, no daily quota.

How to Use Extract Audio from Video

  1. Upload a video file — Drop an MP4/MOV/MKV/WebM file up to 500 MB.
  2. Choose output format — MP3 (universal), WAV (uncompressed), OGG (open), FLAC (lossless), AAC (high quality).
  3. Download the audio track — FFmpeg extracts the audio stream and re-encodes (or copies, for matching formats) to the chosen format.

Frequently Asked Questions

Will quality be preserved?

WAV/FLAC are lossless. MP3/AAC at 192 kbps+ is transparent for most listeners. Lower bitrates lose quality.

What if the video has multiple audio tracks?

PrivaTools extracts the first/default audio track. Multi-track extraction is on the roadmap.

Can I extract just a section of the audio?

Use Trim Media first to isolate the section, then extract audio from the trimmed video.
