ConvertWhat happens when you convert MOV to M4R
- The result is an M4R ringtone: AAC audio that iPhone lists under Ringtones once it's on the phone.
- iPhone only takes ringtones up to 40 seconds, so the audio is cut at 40 seconds with a short fade-out. Untick “Trim to 40 seconds” to keep the full length.
- 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.
- 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 M4R reduce quality?
M4R 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.
How long can an iPhone ringtone be?
Up to 40 seconds; longer files don't show up as ringtones. Text and alert tones work best under 30 seconds.
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.
Are tags and cover art kept?
Not yet. The sound is converted, but title, artist and album art aren't copied.
