How to make an iPhone ringtone from any song

The full M4R workflow Apple never explains: cut, fade, sync — plus the Android version that takes one step.

The song is on your phone; making it your ringtone somehow involves three apps and a cable. Here is the honest, complete workflow — the cut takes a minute in your browser, and the one genuinely annoying step (Apple's sync requirement) is explained rather than hidden.

Step 1 — cut the clip

  1. Open the MP3 Cutter & Ringtone Maker and drop the song (MP3, M4A, WAV — even a video works; its audio is used).
  2. Play it, and press Set start here at the moment the good part begins — usually the chorus. Mark the end the same way. Aim for 15–25 seconds; iPhone requires under 40.
  3. Choose M4R (iPhone) as the output — or MP3 for Android — leave the fades on, and cut. The result plays in the page so you hear exactly what you'll get.

The song never uploads — cutting runs entirely in your browser.

Step 2 (iPhone) — the sync Apple requires

Connect the iPhone to a computer. On a Mac, open Finder, select the phone, and drag the .m4r file onto it. On Windows, iTunes does the same job. The tone then appears under Settings → Sounds & Haptics → Ringtone. No cable available? Open this guide on the phone, cut the clip as M4A, and import it via GarageBand's share-as-ringtone feature — clumsier, but cable-free.

Step 2 (Android) — one step

Cut as MP3 on the phone's own browser, and pick the file under Settings → Sound → Phone ringtone. Done.

Make it sound professional

Start the cut a beat before the hook so the fade-in finishes as the hook lands. If the source is quiet, run it through the Volume Booster (Normalise mode) before cutting — ringtones compete with pockets and traffic. And keep the original file: re-cutting from a fresh source always beats re-cutting a cut.

Frequently asked questions

Why must an iPhone ringtone be under 40 seconds?

Apple’s ringtone format (.m4r) is rejected by iOS when the audio runs longer than 40 seconds. The cutter warns you when a selection is too long — most great ringtones are 15–25 seconds anyway.

Why can’t I just download a ringtone straight to the iPhone?

Apple provides no direct route: every ringtone — from any site or app — reaches the phone via Finder (macOS) or iTunes (Windows), or via GarageBand on the phone itself. Sites that claim otherwise end with the same sync step.

How do I set a custom ringtone on Android?

Far simpler: cut the clip as MP3, save it on the phone (this site works fine in a phone browser), then Settings → Sound & vibration → Phone ringtone → pick the file.

Is the song uploaded anywhere while cutting?

No — the cut happens in your browser with FFmpeg compiled to WebAssembly. Your music never leaves the device, and the tool keeps working offline once loaded.

Why does my cut click or start abruptly?

A raw cut lands mid-waveform. Leave the fade in/out option on — 0.8-second fades make any cut sound intentional, which is exactly how commercial ringtones are produced.
