Convert MOV to MP3

About converting MOV to MP3

MOV (.mov) files can be converted to MP3 entirely in your browser — no software to install, no file upload, and no account required. The conversion runs on a WebAssembly build of ffmpeg directly on your device.

How to convert MOV to MP3 privately

Every step below runs on a WebAssembly build of ffmpeg inside this browser tab. Your .mov file is never uploaded to a server — there's no network request carrying it anywhere.

  1. Add your MOV file

    Drag and drop, or click to select, a file (.mov). It's read straight from disk into browser memory — no upload step exists.

  2. Convert locally

    FreePrivateConvert converts it to MP3 using a WebAssembly build of ffmpeg, entirely within this browser tab.

  3. Download the result

    Save your converted .mp3 file. It only ever existed in this tab's memory — closing the tab without downloading discards it completely.

Convert MOV to MP3 with ffmpeg (command line)

Prefer the terminal? This is the exact ffmpeg command this page runs for you:

ffmpeg -i input.mov -vn -c:a libmp3lame -q:a 2 output.mp3
-i input.mov
Your MOV file.
-vn
Drop the video track and keep only the audio.
-c:a libmp3lame
Encode the audio as MP3 (LAME encoder).
-q:a 2
Variable-bitrate MP3 quality 2 on a 0-9 scale (lower is better; 2 is roughly 190 kbps).
output.mp3
The MP3 file to create. ffmpeg picks the container from this extension.

Don't have ffmpeg installed? You don't need it: use the converter at the top of this page. It runs the same conversion on your own device, and your file is never uploaded.

FAQ

Is my file uploaded anywhere?
No. Your file is read and processed inside this browser tab and never leaves your device. You can confirm it in your browser's developer tools: the Network tab shows no upload.
Does converting MOV to MP3 reduce quality?
MP3 is lossy and the video's soundtrack was already compressed, so this is a second lossy encode, at LAME's high-quality VBR setting (-q:a 2, around 190 kbit/s). Most listeners won't hear a difference, especially for speech.
Is there a file size limit?
Yes: 500MB per file. There's no account and no limit on how many files you convert.
What's the difference between MOV and MP3?
MOV (QuickTime Movie) and MP3 (MPEG-1 Audio Layer III) store data differently. MOV: lossy (codec-dependent, typically H.264; can wrap low-compression ProRes). MP3: lossy. MP3 is the most widely compatible lossy audio format — plays on essentially every device and app made in the last two decades.
Why convert MOV to MP3?
Common uses for MP3: Podcasts and audiobooks; Music distribution and downloads; Extracting audio from video. Universal hardware and software decoder support, making it the safest choice for compatibility.
What MIME type does a .mp3 file use?
audio/mpeg, the standard type for MPEG-1 Audio Layer III.
What is the ffmpeg command to convert MOV to MP3?
Run: ffmpeg -i input.mov -vn -c:a libmp3lame -q:a 2 output.mp3. This is the exact command FreePrivateConvert runs for this conversion, so you can use this page instead of installing ffmpeg: it runs the same conversion inside your browser.
