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
- Open the MP3 Cutter & Ringtone Maker and drop the song (MP3, M4A, WAV — even a video works; its audio is used).
- 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.
- 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.
