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. Nothing is uploaded. Open your browser's network tab while you convert and you will see your file never leaves the page. Once the converter itself has downloaded, it keeps working on this device even with no connection.
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.
