Frequently asked questions
How do I make a ringtone?+
Select the 20–30 second highlight of a song and cut it. On Android, set the MP3 as your ringtone directly. On iPhone, save as M4R and add it via iTunes (Finder) or GarageBand.
Are my files uploaded to a server?+
No. Cutting happens entirely inside your browser and your file is never sent anywhere.
Will the quality drop?+
The selection is re-encoded at a bitrate matching the original, so any difference is practically inaudible.
What are fade in and fade out?+
Fade in starts the clip quietly and ramps up; fade out ends it by ramping down. They make mid-song cuts sound natural instead of abrupt.
Is there a length limit?+
No — cut anything from a 1-second sound effect to a long passage. Note that iPhone ringtones must be 40 seconds or shorter.
Can I use the clip anywhere?+
Personal ringtones and private use are generally fine, but publishing or commercial use (e.g. YouTube uploads) requires permission from the song's rights holder.
Guide
Making a phone ringtone
Android is straightforward: cut your selection as MP3, download it, then pick it under Settings → Sound → Ringtone. On Galaxy phones, moving the file into the Ringtones folder makes it appear automatically.
iPhone only accepts M4R ringtones up to 40 seconds. Cut your selection as M4A, rename the extension to .m4r and sync via iTunes (Finder on Mac), or import it in the GarageBand app and export as a ringtone.
Picking the right section
For ringtones, 20–30 seconds starting just before the chorus works best. The waveform usually swells where the chorus begins, so use its shape as a guide.
Cutting from the middle of a song can start and end abruptly. Add a 0.5–1s fade in and a 1–2s fade out for a much smoother result.
What makes this cutter different
Typical online cutters upload your file to a server. This tool runs the FFmpeg engine as WebAssembly inside your browser instead — your file never leaves your device, private recordings stay private, and there's no upload queue to wait for.
