How do I get the audio out of an MP4?

Drop the MP4 into Extract Audio from Video, choose MP3, WAV or M4A, and click Extract audio. The soundtrack is pulled out on your own device and downloads as an audio file — nothing is uploaded.

Which audio format should I pick — MP3, WAV or M4A?

Pick MP3 for a small file that plays everywhere, WAV when you need lossless quality for editing, and M4A for compact AAC audio that plays natively on iPhones and Macs.

Can I turn a meeting or lecture recording into a podcast file?

Yes. Load the recording, choose MP3 or M4A, and export an audio-only file ready for a podcast feed or your music player. Because it runs locally, even confidential recordings stay on your device.

Does extracting audio send my video to a server?

No. The tool decodes and re-encodes the audio entirely in your browser. Your video is read from your device and is never uploaded to ArrayKit or anywhere else.

Will the sound quality drop when I extract it?

Choose WAV to keep the audio lossless. MP3 and M4A are compressed, so pick a format based on whether small size or maximum fidelity matters more for your use.

Is there a limit on the length of video I can use?

There is no imposed file-size limit, so you can load a recording of any length. The practical ceiling is your device's memory, since the audio is extracted locally in one browser tab.

About Extract Audio from Video

Extract Audio from Video pulls the soundtrack out of a video file and saves it as an audio file, right in your browser. Load a clip, pick MP3, WAV or M4A, and the audio track is decoded and re-encoded on your own device — no uploads, no waiting in a queue. MP3 gives you a small, universal file; WAV keeps lossless quality for editing; M4A is compact AAC that plays natively on phones and Macs. It reads common containers like MP4, MOV, MKV and WebM and discards the picture entirely, so you keep only the sound. Great for turning a talk, lecture or meeting recording into a podcast-ready file, grabbing background music, or building an audio-only version of a screen recording. Nothing is sent to a server, so even sensitive recordings stay private.

Common errors & troubleshooting

The exported audio is silent. — The source video may have no audio track, or its audio uses a codec that could not be decoded. Confirm the original plays with sound, then try again.
The WAV file is very large. — WAV is uncompressed and lossless, so it is big by design. Choose MP3 or M4A if you want a much smaller file for sharing.
Extracting audio from a long video is slow. — The whole track is decoded locally in a single browser tab. Trim the video to the part you need first, or leave the tab open while it finishes.
The video will not load or errors out. — The source may use an unsupported or DRM-protected codec. Try a standard MP4, MOV, MKV or WebM file.
