About Video to Audio (MP3)
Video to Audio extracts the soundtrack from a video and saves it as an MP3, M4A, or WAV — right in your browser. Upload a video, choose a format, and download just the audio in a click.
It runs an in-browser build of ffmpeg, so your video is processed entirely on your own device and never uploaded to any server. It's free, with no sign-up and no watermark.
Frequently asked questions
- Is it free to use?
- Yes — it's completely free with no sign-up, no watermark, and no limits.
- Is my file uploaded to a server?
- No. It runs an in-browser build of ffmpeg, so your file is processed entirely on your own device and never uploaded.
- Why does the first run take a moment?
- The first time, it downloads a ~32 MB processing engine. That's cached afterwards, so later runs start instantly.
- What formats can I convert?
- It reads common video formats like MP4, MOV, WEBM and MKV, and outputs MP3, M4A (AAC), or WAV audio.
- How big a video can it handle?
- It works on your device's memory, so very large files (roughly over 1–2 GB) may be slow or run out of memory, especially on phones. Shorter clips are fast.
