How to extract audio from a video
- Choose your video.
- Pick the format: MP3 plays everywhere; M4A often copies the original sound with no loss.
- Press Extract and download the audio file.
Which format?
| Format | Best for | Quality |
|---|---|---|
| MP3 | Any player, car, phone | Re-encoded at the bitrate you choose |
| M4A (AAC) | Apple devices, small files | Copied as it is when the video has AAC sound (most do) |
| WAV | Editing in audio software | Uncompressed, large files |
| OGG (Opus) | Small files with good quality | Re-encoded |
Good to know
- Opens MP4, MOV, M4V, WebM, MKV and MPEG-TS.
- MP3 is made with the LAME encoder, built into this page.
- This works on video files on your device. It can't download from YouTube or other websites.
- No server-imposed file size limits. The new file is made in your device's memory, so very long videos need a computer with enough free memory.
