What Is a Ringtone Cutter?
A ringtone cutter is an MP3 cutter built for one job: keeping the 15 to 40 seconds of a song you want to hear when your phone rings, with clean edges, in a file your phone accepts. A plain audio editor stops at the cut. This one also knows that an iPhone wants an M4R of 40 seconds or less, that Android is happy with an MP3, and how to set the result as your ringtone. It fixes the usual problems:
- The part you love starts at 1:12, not at 0:00
- A clip that starts mid word or ends with a click
- An iPhone that wants M4R ringtones of 40 seconds or less
- Cutter sites that upload your song or stamp a watermark on it
- Phone apps that hide the trim button behind ads
Why Use This Ringtone Cutter Instead of a Plain MP3 Cutter
This ringtone cutter puts everything a phone ringtone needs on one screen, with nothing to install.
A Waveform You Can Grab
Drag either handle, slide the shaded band to move the whole selection, or draw a new one anywhere on the song. Click anywhere to move the playhead there.
Exact to 0.1 Second
Type the start and end, nudge them with the minus and plus buttons, or move the selection with the arrow keys: 0.1 second per press, 1 second with Shift.
Ringtone Lengths in One Tap
Pick 15, 20, 30 or 40 seconds, or drag to any length. The selection starts on the liveliest part of the song, and Find best part finds it again.
Fades, Boost and Normalize
Fade in and out over 0 to 5 seconds, raise a quiet song by up to 12 dB behind a limiter, or switch on Normalize loudness to even it out.
Formats Your Phone Accepts
Save M4R for iPhone, MP3 for Android, M4A or WAV. M4R is held to 40 seconds with a short fade, so it fits the iPhone limit.
Private, Free, No Watermark
The song cutter works on your own phone or computer and never uploads a file. No account, no daily cap, nothing stamped on it.
How to Use the Ringtone Cutter in Three Steps
The ringtone cutter works the same on Windows, Mac, Chromebook, iPhone and Android, in Chrome, Safari, Edge or Firefox.
- 1
Open a song or video
Drop an MP3, WAV, M4A, AAC, OGG or FLAC file, or an MP4, MOV or WebM video for its sound, up to 100 MB. No file handy? Tap Try a sample for an original tune.
- 2
Choose the part
The selection lands on the liveliest 30 seconds. Drag the handles, type exact times or tap 15, 20, 30 or 40 seconds, and loop it until it sounds right.
- 3
Download the ringtone
Pick M4R or MP3, keep the suggested name (song-ringtone) or type your own, and download. A card then shows how to set it on iPhone or Android.
Ringtone Cutter Features for a Clean, Exact Cut
An MP3 cutter built for the 30 seconds that matter, from a pop chorus to a voice memo.
Trim to the Exact 0.1 Second
Zoom into the waveform until single beats are wide enough to grab, then set the start right on the downbeat. Every time field in the ringtone cutter reads to a tenth of a second, the arrow keys move the whole selection by 0.1 second (1 second with Shift), and I and O set the start and end at the playhead while you listen. This is how an MP3 trimmer should feel: Space plays, L loops, P plays the selection from the top, and Ctrl or Cmd plus Z undoes any step. Use it as an MP3 trimmer online on a laptop, or drag the handles with a finger on your phone.
Set My Start PointRingtone Lengths: 15, 20, 30 or 40 Seconds
Most ringtones sit between 20 and 30 seconds, long enough for the hook to land. In the ringtone cutter, tap a length and the end handle moves for you, or drag to any length from 1 second up. As a song cutter it also works the other way round: slide the 30 second band along the track to audition different choruses, then tap Find best part to jump back to the liveliest stretch. If you choose M4R, the clip is held at 40 seconds, the most an iPhone accepts, and a note tells you when it had to shorten it.
Pick a LengthFades, Volume Boost and Normalize
A hard cut in the middle of a bar sounds like a glitch on a phone speaker. Add a fade in and a fade out of up to 5 seconds and the ringtone eases in and out; the ringtone cutter already gives new clips of 4 seconds or more a 1 second fade out. Quiet acoustic track? Raise it by up to 12 dB while a true peak limiter holds the peaks at -1 dB, so it gets louder without crackling. Or switch on Normalize loudness, which measures the clip and sets it to about -12 LUFS, a touch hotter than streaming apps. For a tone you can hear on a busy street, the loud ringtone page opens with the boost already on.
Add a FadeM4R, MP3, M4A or WAV From One Song Cutter
Pick the format for your phone. M4R is the iPhone ringtone file, encoded as AAC at 192 kbps with a title tag, and the iPhone ringtone maker walks through the setup. MP3 at 192 kbps rings on any Android phone; the Android ringtone maker covers the settings. M4A suits GarageBand, and WAV keeps every sample for more editing. The MP3 cutter also opens the sound inside MP4, MOV and WebM files, so a clip from your camera roll works as well as a song, and video to ringtone has tips for that.
Choose a FormatRingtone Cutter Example: Cut 30 Seconds From a Sample Song
Slide the selection, tap a length and switch formats to see the exact clip you would download.
The ringtone cutter at the top does the same with your own file and real audio. In this demo, as in the real export, M4R stops at 40 seconds while MP3 keeps any length, and the file name follows the song. Only use songs you own or have the rights to.
What Makes This MP3 Cutter Different
Four details you notice once the ringtone is on your phone.
Nothing Is Uploaded
Decoding, cutting and encoding all happen in your browser, so a private voice memo stays private.
Real M4R, Not a Renamed MP3
The iPhone file is genuine AAC audio, encoded on your device by the browser or a built-in fallback. If neither works, the cutter says so and offers MP3.
Cut the Next Part
After a download, one tap moves the selection to the next stretch of the same length: handy for a verse, a chorus and a bridge from one song.
Undo Everything
Every drag, fade and volume change goes into the history. Step back with Ctrl or Cmd plus Z, and forward again with Shift added.

Ringtone Cutter FAQ
Straight answers about trimming songs for iPhone and Android.
What is a ringtone cutter?
A ringtone cutter is a tool that trims a song or recording to the short part you want to hear when your phone rings and saves it in a phone format. RingtoneGenerator does it in your browser: pick 15 to 40 seconds on the waveform, add fades and download M4R for iPhone or MP3 for Android.
Is this ringtone cutter free?

How long should a ringtone be?
Aim for 20 to 30 seconds. An iPhone accepts ringtones of up to 40 seconds (GarageBand stops at 30), so the cutter holds M4R files at 40. Android plays an MP3 of any length, and the ringtone simply repeats while the phone rings.
Can I use it as an MP3 cutter online for other clips?
Yes. It is a full MP3 cutter online and a music cutter online: MP3, WAV and M4A files can be cut and saved at any length, not only as ringtones. Only M4R is capped at 40 seconds.

Yes, for any song saved on your device. It is a music cutter online, free of charge, that opens MP3, WAV, M4A, AAC, OGG and FLAC files up to 100 MB. It cannot fetch songs from streaming apps or links.
Does the online MP3 trimmer work on iPhone and Android?
Yes. The online MP3 trimmer runs in Safari, Chrome and other modern browsers on phones, tablets and computers. On a phone you drag the handles with a finger, and the file lands in Files or Downloads.
Which files can I open?
MP3, WAV, M4A, AAC, OGG and FLAC audio, plus the sound of MP4, MOV and WebM videos, up to 100 MB per file. If your browser cannot read a file, the ringtone cutter tells you; an MP3 or WAV copy will open.
Which formats can I save?
M4R (AAC, 192 kbps) for iPhone, MP3 (192 kbps) for Android, M4A (AAC, 192 kbps) and WAV (16 bit). Nothing is watermarked, and the file name starts as the song name plus -ringtone. Turning a whole folder into iPhone tones? The batch MP3 to M4R converter does many files at once.
Why is my M4R shorter than my selection?
Because an iPhone ringtone can be at most 40 seconds. When you pick M4R, the selection shrinks to 40 seconds and the end gets a fade out of at least half a second, so the repeat does not click.
Are my songs uploaded anywhere?
No. The ringtone cutter reads, cuts and encodes the file inside your browser and saves the result straight to your device. Only AI Generate talks to a server, after you sign in.

On iPhone, drag the M4R onto your phone in Finder on a Mac, or in Apple Devices or iTunes on Windows, then pick it in Settings > Sounds & Haptics > Ringtone; if it does not show up, use GarageBand or, on iOS 26 and later, the Files app (Share > Use as Ringtone, up to 30 seconds).
