ConvertWhat happens when you convert MOV to MP3
- Only the sound is converted; the video is left out.
- Both formats are lossy. Re-encoding loses a little quality, so pick a bitrate at least as high as the original's.
- MP3 encoding uses the open-source ffmpeg engine, downloaded once (about 31 MB) and run on your device.
- Mono and stereo are kept (or choose either); surround sound is mixed down to stereo.
- Tags such as title, artist and cover art aren't copied yet.

Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many MOV files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting MOV to MP3 reduce quality?
MP3 removes sounds most people can't hear to make the file smaller. At the default bitrate most listeners won't notice a difference; pick a higher bitrate to be safe.
Can I extract the audio from MOV videos?
Yes. Drop the video and only its sound is converted. The video never leaves your device.
Which bitrate should I choose?
For music, 192 kbps MP3 or 160 kbps AAC sounds near-identical to the original, and Opus sounds great at 128 kbps. For speech and podcasts, 64–96 kbps is plenty.
Why does the first MP3 conversion take longer?
Browsers can't create MP3 files on their own, so the converter downloads the open-source ffmpeg engine once (about 31 MB). After that it's cached and starts right away.
Are tags and cover art kept?
Not yet. The sound is converted, but title, artist and album art aren't copied.
