MOV to MP3 Converter
Pull the audio out of a QuickTime MOV and save it as an MP3 — an iPhone recording, a camera original, or a ProRes master with uncompressed sound. No QuickTime install, and nothing leaves your machine.
What a MOV carries, and why it varies so much
| What the audio usually is | AAC on anything from a phone or a camera, and sometimes uncompressed PCM on footage straight out of a professional deck or ProRes workflow. |
|---|---|
| When the file is enormous | A MOV with PCM audio carries it uncompressed. Converting that to MP3 is the one case where the audio genuinely shrinks by an order of magnitude rather than merely changing shape. |
| iPhone and QuickTime recordings | These are AAC in a MOV wrapper. Extracting to MP3 works, but copying to .m4a keeps the original quality and skips the re-encode entirely. |
| Multiple audio tracks | Camera MOVs often carry more than one track — a shotgun mic and a lav, say. The extractor lists each one so you can convert them separately instead of getting whichever came first. |
MOV is Apple's container and the direct ancestor of MP4 — the two are close enough that a MOV holding AAC and H.264 is, structurally, an MP4 with a different label. The difference that matters here is what professional workflows put inside a MOV, which is often not compressed at all.
Phone footage or camera footage?
From a phone. The audio is already AAC at a modest bitrate. Converting to MP3 works, but it re-compresses audio that was compressed once already. If the destination takes AAC, copy the track out as an .m4a instead — instant, and bit-identical to what the phone recorded.
From a camera or a deck. Here MP3 earns its place. An uncompressed PCM track converted to MP3 loses very little that anyone will hear and gets an order of magnitude smaller, which is the one situation where converting is straightforwardly the right call.
Not sure which you have? Drop the file in — the tool reads the streams and names the codec, sample rate and channel count before you convert anything. The audio extractor exposes every format if you want something other than MP3.
Frequently asked questions
Can I convert an iPhone video to MP3?
Yes. An iPhone recording is AAC audio inside a MOV or MP4 wrapper, and both work here. Drop the file in and convert — nothing is uploaded, which matters more than usual for footage taken on a personal phone.
Why is my MOV file so much larger than an MP4 of the same clip?
Professional MOV files often carry uncompressed PCM audio and a lightly compressed picture such as ProRes, because they are working files rather than delivery files. The audio alone can be ten times the size of the equivalent AAC, which is why converting it to MP3 shrinks it so dramatically.
My MOV has two audio tracks. Which one gets converted?
Whichever you pick. Camera MOVs frequently carry a shotgun mic on one track and a lav or scratch mic on another, so the tool lists every audio stream with its codec, sample rate and language tag rather than silently taking the first.
Does QuickTime need to be installed?
No. The MOV is parsed by ffmpeg compiled to WebAssembly, running inside the page. There is nothing to install on Windows, macOS or Linux, and the tool behaves the same on all three.
What is the largest MOV I can convert?
Up to 200.0 MB. That limit is about browser memory rather than the format — the file is held in the tab while the audio is pulled out of it, so a long ProRes master is the most likely thing to hit the ceiling.
