Video to audio converter
Pull the soundtrack out of a video file, from a screen recording to a music video. When the video already has AAC audio, M4A output copies it without re-encoding, which is fast and lossless.
1. Choose a video
2. Extract the audio
The audio is encoded as MP3 at 320 kbps.
How it works
- Pick a video file from your device.
- Choose MP3, M4A, or WAV. M4A keeps AAC audio as it is, without re-encoding.
- Extract the audio. The video is read on your device and never uploaded.
Frequently asked questions
Which video formats can I use?
Most common formats work, including MP4, MOV, M4V, MKV, WEBM, and AVI, as long as the video has an audio track.
Which output format should I choose?
MP3 plays everywhere. M4A is the fastest and keeps the original quality when the video has AAC audio, which most MP4 and MOV files do, because the audio is copied instead of re-encoded. WAV is uncompressed, for editing software.
Is there a file size limit?
There is no fixed limit, but processing happens in your browser’s memory. Videos up to a few hundred megabytes work well; very large files, especially on phones, can run out of memory.
Is my video uploaded anywhere?
No. The video is read directly from your device by the converter running in your browser, and it never leaves your computer or phone.
Is this tool free?
Yes. It is completely free, with no account, no watermark, and no limit on how many files you process.
