Free Audio Extractor — Rip Audio from Video
Extract audio tracks from any video file — a free alternative to Adobe Premiere Pro. No sign-up, no watermarks, no limits.
Extract the audio track from any video file — MP4, MOV, MKV, WebM, AVI — and save it as MP3, M4A, WAV, OGG, or FLAC. Runs entirely in your browser via ffmpeg.wasm with no upload, no account, and no length limit beyond browser memory. A free alternative to VLC's convert/save and Adobe Audition's import-from-video for ripping audio out of a video.

Multiple Output Formats
Extract to MP3, M4A, WAV, OGG, or FLAC. Or keep the original codec with zero-loss stream copy.
Instant Stream Copy
Original mode copies the audio track without re-encoding — near-instant extraction with zero quality loss.
Quality Control
Choose bitrate from 64 kbps to 320 kbps for lossy formats. Lossless formats (WAV, FLAC) preserve full quality.
100% Private
All processing happens in your browser using WebAssembly. Your files never leave your device.
Free Audio Extractor — Rip Audio from Video Files Online
The Free Audio Extractor lets you pull the audio track from any video file — directly in your browser. Convert to MP3, M4A, WAV, OGG, or FLAC, or use stream copy to keep the original codec with zero quality loss. No sign-up, no uploads, no file size limits.
Once you have the audio extracted, trim out the parts you need with the free audio trimmer, or re-encode at a different bitrate via the free audio converter.
Features
- Stream copy mode— "Original" mode copies the audio track without re-encoding. Near-instant extraction with zero quality loss.
- 5 output formats — MP3, M4A (AAC), WAV, OGG (Vorbis), and FLAC. Lossy and lossless options for every use case.
- Bitrate control — Choose from 64 kbps to 320 kbps for lossy formats. Lossless formats preserve full audio quality automatically.
- Video preview — Watch the video before extracting to confirm you have the right file.
- 100% client-side — Uses ffmpeg.wasm (WebAssembly). Your files never leave your device.
How to Extract Audio from a Video
- 1. Add a video — Drag and drop a video file into the upload area, or click to browse. MP4, WebM, MOV, AVI, and MKV are supported.
- 2. Choose format— Select your desired audio format. Use "Original" for the fastest, lossless extraction.
- 3. Set bitrate — For lossy formats (MP3, M4A, OGG), choose a bitrate. 128 kbps is standard; 320 kbps is maximum quality.
- 4. Extract— Click "Extract Audio". Stream copy is nearly instant; re-encoding takes longer depending on file length.
- 5. Download — Download your extracted audio file.

Tips, Mistakes & Takeaways
Tips
- →Extract to FLAC or WAV first if you'll re-edit the audio later — lossless preserves your editing headroom.
- →Use M4A (AAC) for the smallest file when you only need playback quality.
- →Check the source video's audio sample rate — extracting to a higher rate doesn't add information.
- →If the source has multiple audio tracks (multi-language), the extractor takes the first track by default.
Common Mistakes
- !Extracting MP3 from a video whose audio is already MP3 — that's a re-encode that loses quality without benefit.
- !Forgetting that very long videos hit browser-memory caps — split a 2-hour movie if your browser warns you.
- !Expecting noise reduction or normalization — extraction is a passthrough, not a clean-up pass.
Key Takeaways
- ✓Single-pass audio rip from any common video container into any common audio format.
- ✓Local-only via ffmpeg.wasm — your video never leaves the browser.
- ✓Pure extraction — no audio cleanup, normalization, or denoising included.
Frequently Asked Questions
When should I use "Original" vs. a specific format?
Use Original when you want the fastest extraction with no quality loss — the audio is copied byte-for-byte. Choose a specific format when you need compatibility (e.g. MP3 for older devices) or want to change the codec.
Why did stream copy fail and fall back to AAC?
Stream copy requires the original audio codec to be compatible with the output container. If the video uses an uncommon codec, the tool automatically falls back to AAC re-encoding to ensure you get a working output file.
Can I extract from very large video files?
Yes, but the entire file must be loaded into browser memory via WebAssembly. Files up to ~2 GB work well on most modern machines. The loading step may take a moment for large files.
