Extract Audio from Video is JavaScript that your browser has already downloaded, and it does the whole job on your own machine. On a normal site, a 5 GB video means 5 GB uploaded, a wait in somebody's queue, and 480 MB downloaded again. Here it means 0 bytes up and 0 bytes down.

How to use Extract Audio from Video
- 1. Upload the video and review the analysis. Drop or browse for the MP4 or MOV file. Videos up to 5 GB work: the file is read in small chunks rather than loaded whole, and it never leaves your device. The tool instantly analyzes the video and shows its duration alongside the audio track's codec, bitrate, channels and sample rate.
- 2. Choose M4A or MP3. M4A copies the existing compressed audio stream bit-for-bit into an .m4a file, which is instant and completely lossless. MP3 re-encodes the track with the LAME encoder so it plays on absolutely everything; pick 128, 192 or 320 kbps depending on how much quality you want to keep.
- 3. Extract and download the audio. Press Extract audio. The M4A path finishes in seconds; MP3 shows a progress bar while it encodes. Listen to the result on the page, check the reported size and codec, then download the audio file, named after the video with the new extension.
When to use Extract Audio from Video
Extract Audio from Video pulls the soundtrack out of an MP4 or MOV as a standalone audio file, entirely in your browser with nothing uploaded to any server. The default M4A mode is lossless and instant, while MP3 mode trades a quick re-encode for universal playback. Use it whenever you want the sound without the picture.
- Turning recorded talks into listenable audio. A lecture, webinar or meeting recording is mostly worth its audio; extracting it produces a small file you can play in a podcast app during a commute instead of keeping a huge video open.
- Saving music from a concert or event video. Phone videos of live performances capture audio you may want on its own; a 320 kbps MP3 plays in the car, on old players and everywhere else the video would not.
- Getting audio for transcription or editing. Transcription services and audio editors want an audio file, not a multi-gigabyte video; the lossless M4A copy hands them exactly the original track with nothing lost on the way.
- Ripping audio from private footage safely. Online extractors upload your whole video to their servers just to return a few megabytes of sound; this tool does the extraction locally, so interviews and personal recordings stay on your machine.
