Extract Audio from Video
Extract the audio track from a local video as MP3 or WAV. Your files are never uploaded to our servers. ToolkitPoint processes them on your own computer, so confidential documents stay with you.

How to use Extract Audio from Video
- Choose one or more videos under "Choose local video files"; the page lists every audio track (language, codec, channels, bitrate) and any chapters.
- Leave "Audio format" on "Original audio, no re-encode" to copy the soundtrack unchanged (fastest, no quality loss), or pick MP3, WAV, FLAC, AAC (M4A) or OGG Vorbis.
- Tick the audio tracks to extract (each becomes its own file), optionally enter a start and end time, or tick "Split by chapters".
- Check the size estimate and the copy-versus-re-encode note; "Bitrate" is only enabled for MP3, AAC and OGG.
- Press "Extract audio" and download each file, or the ZIP when there are several.
Worked example
Choose a 3-minute MKV with English and Spanish audio, tick both tracks and leave Original audio selected. You download a ZIP with movie-track1-eng.m4a and movie-track2-spa.m4a copied without re-encoding. Or tick Split by chapters and choose MP3 at 192 kbps to get one MP3 per chapter.
When to use this tool
- Saving the music from a concert video as a WAV to edit in a DAW.
- Pulling a podcast episode out of a recorded video call as MP3.
- Making a compact AAC copy of a talk for listening on a phone.
Important limitations
Extraction runs through FFmpeg WebAssembly on your computer, one output at a time; files larger than 250 MB are refused and very large videos can exhaust device memory. Copy mode only works when the audio codec can live in a standalone file; otherwise choose MP3 or WAV.
Frequently asked questions
Does the bitrate setting affect WAV and FLAC?
No, and the menu is disabled for them and for the copy mode. Only MP3, AAC (M4A) and OGG Vorbis follow the chosen kbps.
What does Original audio, no re-encode do?
It copies the audio stream out of the video as it is (AAC becomes .m4a, MP3 stays .mp3, Opus becomes .opus, and so on), so quality is identical and it takes moments. If a codec cannot be copied into a standalone file, pick MP3 or WAV instead.
Can it pull out audio from a video with several tracks?
Yes. The page lists each audio track with its language tag when the video has one. Tick as many as you like; every track becomes a separate file, such as movie-track2-spa.wav.
Can I extract only part of the video, or one file per chapter?
Yes. Enter a start and end time to keep a range, or tick "Split by chapters" when the video has chapters, to get one numbered file per chapter.
How accurate is the size estimate?
It is bitrate times duration: the source's reported audio bitrate for a copy, your chosen kbps for MP3/AAC/OGG, exact PCM size for WAV, and roughly 60% of that for FLAC. Real files differ a little because of headers and variable bitrate.
What happens if the video is silent?
The page tells you there is no audio stream and produces no file. Check that the video actually has sound first.
