About audio extraction
This tool takes any video file and strips out just the audio track. It's useful for ripping the audio off a music video, getting a podcast out of a YouTube download you saved as MP4, or pulling voice-over off a screen recording.
Which format should I pick?
- MP3 — the default. Plays everywhere, small file size, very slight quality loss.
- WAV — uncompressed. Massive files; use when you're going to edit the audio in another tool.
- FLAC — lossless compression. Half the size of WAV, identical quality.
- Opus — modern, best quality-per-byte. Smaller than MP3 at the same quality but not as universal.
- AAC — what iPhones prefer. Slightly better than MP3 at the same bitrate.
FAQ
Does the file get uploaded anywhere?
No. Open this page, turn off your wifi, then try a file — it still works. That's the test.
What's the maximum file size?
Browser memory is the limit. WebAssembly caps at 2–4 GB per file. Most laptops handle 1080p videos under a gigabyte comfortably.
Why is it slow on my phone?
FFmpeg-WASM runs on your CPU, not hardware video encoders. Phones have less CPU, so encoding takes longer.
Can I cancel mid-encode?
Yes. The Cancel button terminates the worker immediately. You'll wait a few seconds the next time you start.
