Extract Audio from Video, Free nothing stored

MP4 to M4A keeps a recording ready for listening

Use the soundtrack separately when you want to listen to a recorded lesson, edit an interview or reuse location sound. Add the local recording and choose M4A or WAV under Format; the default is M4A.

M4A output contains AAC audio. If the source already carries AAC, the engine copies that sound without decoding and compressing it again. Other audio codecs need conversion, so the file extension alone cannot tell you whether the original sound will be copied.

MP4 to WAV prepares sound for an audio editor

Choose WAV when your editor or next tool needs uncompressed samples. The result uses 16-bit PCM audio. It takes more storage than a compressed soundtrack and does not restore detail already missing from the recording.

There is no sample-rate or bit-depth control on this page. The fallback decoder can resample to the browser’s audio rate, so do not assume every WAV matches the source rate. Read the result statistics before moving it into a project with specific audio requirements.

Read the sound status before reusing the extracted track

After extraction, the result shows the format, duration, file size and sound information. “Original, not re-encoded” identifies the AAC copy path. A sample-rate and channel label appears when the tool converts the sound.

Listen to the preview, including a quiet passage and a louder one. Extraction does not remove hiss, isolate a singer or improve microphone placement. Keep the source recording if you plan to do separate audio repair or mixing.

Long recordings and WebM sound depend on the browser

A phone-class device is limited to 15 minutes and 1 GiB of input per run; a desktop-class device allows 60 minutes and 4 GiB. These are processing ceilings, not guarantees that every file below them will work. Browser memory and codec support still matter.

WebM sound may need conversion to AAC for M4A output. If the browser cannot do that, choose WAV or try an updated browser. The WAV fallback that reads the whole source into memory has a separate 300 MiB input cap. For oversized recordings, use Video Trimmer to prepare a shorter source first.

Extract a personal recording where the file already lives

The processing path reads your chosen file as a local browser blob and builds a separate audio file in memory. Your recording is not uploaded for extraction, and the original video is not overwritten. Extracting the soundtrack locally still involves loading the audio tool’s code and making website service requests.

Start with a file on your device. This page has no field for downloading a YouTube or social-media link. A video without an audio track has no recorded sound for the tool to extract.

Decide what happens after the soundtrack is separate

This page extracts the full recording. Use Audio Trimmer for a shorter sound clip or fades, and Audio Converter when your starting file is already audio. If you want the picture with no sound, use Mute Video instead.

For spoken words as text, the linked Video Transcriber works from the original video. If you are also keeping the picture, the linked 4K Video Enhancer handles video upscaling. Neither job is performed by saving an audio file here.

How do you use the video to audio?

1. Choose the source recording

   Add a local file. Extract sound from a MP4, MOV, WebM, MP3 or WAV video with a readable audio track.

2. Set the sound format

   Keep M4A for an AAC audio file, or select WAV when your next editor needs uncompressed sound.

3. Extract and listen

   Press Extract audio, play the result and check its duration and sound status.

4. Save your result
