Quick Answer

To extract audio from a video, upload the file here, choose MP3, WAV, AAC or OGG, and click Extract Audio — the soundtrack is ready to preview and download in seconds. Pick MP3 if you just want a file that plays everywhere, WAV if you are going to edit or master the audio and want no further loss, AAC for the best quality-per-megabyte, and OGG if you need an open format for the web. The extraction runs in your browser through FFmpeg.wasm, so the video never leaves your device, and there is no watermark, no account and no length limit beyond your own memory.

Common Use Cases

Saving music or a soundtrack from a video

Turn a recorded performance, a rehearsal video or a lecture into an audio file you can play in the background or on a phone.

Making a podcast episode from a video recording

Interviews and webinars are often recorded on video; extracting the audio gives you the podcast master directly.

Transcription and note taking

Speech-to-text services generally accept audio and process it faster and cheaper than a full video file.

Grabbing sound effects and ambience

Pull a specific noise, room tone or ambience track out of footage for use in another project.

Listening on the move

An audio-only file uses a fraction of the storage and battery of the original video, which matters for long recordings on a phone.

Editing the sound separately

Extract to WAV, clean it up in an audio editor, then put it back with the Add or Replace Audio in Video tool.

Frequently Asked Questions

How do I extract audio from a video?

Upload the video to this page, select the output format you want from the dropdown, and click Extract Audio. When the progress bar completes, preview the track in the player and click Download Audio.

Should I choose MP3, WAV, AAC or OGG?

MP3 is lossy and plays on virtually every device, which makes it the safe default. WAV is uncompressed and lossless, so it is the right choice if you will edit the audio further, but the files are large. AAC is lossy and gives better quality than MP3 at the same size, and is the native audio in most MP4 videos. OGG (Vorbis) is an open, royalty-free lossy format that is well supported on the web and on Linux.

Will extracting the audio lose quality?

Video soundtracks are already compressed, usually as AAC. Extracting to WAV keeps everything that is there. Extracting to MP3, AAC or OGG re-encodes lossy audio into another lossy format, which adds a small amount of loss; at normal bitrates it is not audible on typical playback equipment.

Is my video uploaded to a server?

No. FFmpeg compiled to WebAssembly runs inside your browser tab, so the video is read from your device, processed locally, and the audio file is written straight back to your downloads.

Does this remove the audio from my original video?

No. Your original file is untouched; the tool only produces a copy of the soundtrack. To create a silent version of the video, use the Remove Audio from Video tool.

What video formats can I extract audio from?

Common containers work, including MP4, WEBM, MOV, AVI and MKV, as far as FFmpeg.wasm and your browser can decode them.

Can I extract only part of the audio?

This tool extracts the whole soundtrack. To keep only a section, extract the full track and then cut it with the Audio Splitter.

How long does extraction take?

Usually a few seconds to a minute. Extracting to WAV is fastest because the audio only has to be decoded; MP3 and OGG take slightly longer because they are re-encoded.

Is it legal to extract audio from a video?

Extracting audio from material you own or created yourself is fine. Copying a soundtrack from someone else's copyrighted video without permission generally is not. Check the rights before you redistribute anything.
