Make a Phone Ringtone from a Song
Pick a song and drag the selection onto the hook — it's cut, leveled and saved as m4r or mp3 in your browser; nothing is uploaded.
Make a ringtone from any song, in your browser
Upload a song, drag the two handles on the waveform (or type Start and End in seconds) onto the hook you want, and download it as a ready-to-use ringtone: m4r — the AAC format iPhone requires — or mp3 for Android and everything else. Leave End empty for the classic 30-second cut starting at Start. The tool also does the two things a raw cut misses: Boost loudness levels the slice to −14 LUFS (EBU R128) so it actually rings loud on a phone speaker, and the short fade-in/fade-out ramps (0.5 s by default) stop the cut from starting or ending with a click. Everything runs locally with ffmpeg compiled to WebAssembly — the song is never uploaded to a server.
Worked example
The chorus of your song starts at 45 seconds. Upload the file, set Start
to 45, leave End empty (that's 45 + 30 = 75 — a standard 30-second
ringtone), keep Boost loudness ticked and both fades at 0.5, and leave
Format on m4r — iPhone. The result is a 30-second, loudness-leveled
AAC ringtone named like the original with a -ringtone.m4r suffix — e.g.
song.mp3 becomes song-ringtone.m4r. For an Android phone, switch
Format to mp3 — Android & others and you get song-ringtone.mp3
instead. Preview it with the play button before downloading.
Formats
- m4r — iPhone (default) — AAC at 192 kbps in the iPod/MP4 container. This is the one format iOS accepts for custom ringtones.
- mp3 — Android & others — 192 kbps mp3; Android, Samsung and most other phones set it as a ringtone directly from the file manager.
Limits and edge cases
- Ringtone length (End − Start) is capped at 40 seconds — iPhone
rejects anything longer — and must be at least 1 second. End empty or
0means Start + 30 s. - Input files up to 10 MiB; anything ffmpeg can decode works (mp3, wav, flac, m4a/aac, ogg, opus — even a video file's audio track).
- If the song ends before your selection does, the ringtone is simply shorter — times past the end of the file are clamped, and the fade-out still lands on the real ending.
- Boost loudness resamples the output to 44.1 kHz (the loudness filter works at a high internal rate); with it off, the source sample rate is kept.
- Fades are 0–5 s per side; set both sliders to
0for a hard cut. Album art embedded in the source is dropped — the output is audio only.
FAQ
How do I get the m4r file onto my iPhone as a ringtone?
Connect the phone and drop the .m4r file onto it in Finder (macOS) or
iTunes (Windows) — it appears under Settings → Sounds & Haptics →
Ringtone. Without a computer, save the file to the Files app and import it
with Apple's free GarageBand app (Share → Ringtone). iOS has no direct
"set as ringtone" for downloaded files, so one of those two steps is always
needed.
How do I set the mp3 as a ringtone on Android?
Copy or download the mp3 to the phone, long-press it in your file manager
and choose Set as ringtone — or move it into the Ringtones folder and
pick it under Settings → Sound → Phone ringtone. Any length works on
Android, but 30 seconds is plenty: the phone loops or cuts it anyway.
Why is my ringtone capped at 40 seconds?
That's iPhone's hard limit — iOS refuses to list ringtones longer than 40 seconds. This tool enforces the same cap for mp3 too, because a ringtone only plays for the ~25–30 seconds a call rings; the 30-second default is the sweet spot on every platform.
What does "Boost loudness" actually do — and when should I turn it off?
It runs EBU R128 loudness normalization (loudnorm) on the cut slice,
targeting −14 LUFS integrated with a −1.5 dBTP true-peak ceiling — the level
streaming services master to. Songs are often mastered quieter, and a quiet
ringtone is a missed call. Turn it off if you're cutting something already
mastered loud, or want the original level and dynamics kept as-is.
Is my song uploaded anywhere?
No. The page downloads an ffmpeg WebAssembly build once and then processes your file locally in the browser tab — the audio never leaves your device.
