Convert MOV to MP3 online

If you recorded something with your iPhone's camera, or exported a clip from QuickTime in MOV, and you really only care about the sound — an interview, a voice memo, the background music in a video — this converter extracts the audio and saves it as MP3 right in your browser, without uploading the video to any server.

What's extracting the audio from a MOV good for?

MOV is the native format of the iPhone camera and of QuickTime on Mac. It's common to end up recording in video when only the audio actually matters: a meeting, a lecture, a quick interview, or that voice memo that accidentally ended up recorded in video mode. Extracting the audio to MP3 gives you a much lighter file than the full video, playable anywhere.

How it works: converted in your browser, not on a server

We use ffmpeg compiled to WebAssembly, running inside your browser tab. When you hit 'Convert', the audio track gets split from the MOV video and encoded as MP3 with libmp3lame, without the video ever leaving your machine. The result downloads directly, just like any other file.

Steps to extract the audio from your MOV

• Choose the MOV file from your device ('Choose file' button).
• Hit 'Convert'. The first time, your browser downloads the conversion engine (a few MB); after that, it's faster.
• Wait for the progress bar to reach 100%.
• Download the resulting MP3 with the 'Download result' button.

The quality comes from the original video, not from the converter

The MP3 you get is exactly what the iPhone's or Mac's microphone captured while recording: if the original audio has background noise, wind, or was recorded too quietly, the converter doesn't fix or improve it — it just extracts and compresses it to MP3. For a clean result, what matters is how the video was recorded, not this conversion.

Honest limits worth knowing

Since the conversion happens in your browser, the real limit is your device's memory when loading the file, not an artificial cap of ours. 4K MOV videos weigh a lot even if you only want the audio, so very long files can take longer to load, especially on phones with limited RAM — try a computer if that happens.

If instead you need the full video in a more compatible container, use MOV to MP4 (instant remux, no re-encoding). And if your file is already in MP4, extract the audio directly with MP4 to MP3. If you don't have the file yet, use our YouTube video downloader.
