Ringtone Cutting Tips
- iPhone ringtones: Must be M4R format, max 30 seconds. Cut your clip to 25-30 seconds, export as M4A, rename to .m4r.
- Android ringtones: MP3 format, no length limit (but 30-45 seconds is standard).
- Start on a beat. Ringtones that start mid-phrase sound jarring. Find a natural starting point.
- Add a short fade-in (0.5 seconds) so the ringtone does not blast at full volume instantly.
Cut your audio — free, instant, no software needed.
