Cut the song.
Keep the part.
Drag across the waveform to trim any MP3, WAV, or audio-from-video — preview it, fade it, and export as MP3, WAV, or an iPhone ringtone (.m4r). All local.
How do I cut an MP3 or make a ringtone? Add the file (audio or video), drag on the waveform to select the part you want, preview, and export — MP3 for Android and sharing, or M4R for iPhone ringtones (up to 40 seconds). Nothing is uploaded.
Audio trimmer
Drag across the waveform to select; drag the edges to fine-tune; drag inside to move the whole selection. Fades are applied on export (and in the preview you'll hear them too). Long files decode fully into memory — under an hour of audio works well on a laptop or phone.
How to trim audio and make ringtones
- Add the file — an MP3, WAV, M4A, or even an MP4/MOV (the audio track is decoded automatically).
- Select the good part — drag on the waveform, press Play selection to check it, and nudge the edges.
- Export — MP3 for Android, sharing, and podcasts; M4R for an iPhone ringtone (iPhone caps ringtones at 40 seconds — the tool tells you if your selection is longer).
Making an iPhone ringtone, honestly
The "30 s ringtone preset" selects the first 30 seconds and turns on the fade-out — a sensible starting point. To install the .m4r on an iPhone: connect it to a Mac (Finder) or PC (iTunes) and drag the file into the Tones section, then pick it in Settings → Sounds. Android is simpler: download the MP3 and set it from any ringtone picker. This is the standard route every ringtone tool uses — no app required, no account, and your song never leaves your device.
What this is good for
- Ringtones and alarms — grab the chorus, fade it out, done
- Podcast and video clips — cut a quote or a segment without a DAW
- Voice notes — trim the dead air before the meeting started
- Sound from video — pull the audio out of a clip and keep only the part you need (or use Video to MP3 for the full track)
Good to know
MP3 export re-encodes once (like every audio editor) — at 192 kbps that's transparent for most listeners. WAV keeps full quality at a bigger size. And since this is a WebAudio-based tool: if a file won't load, it's a codec your browser can't decode — converting it first with Video to MP3 usually fixes that. Cutting a video instead? The video trimmer handles the picture without re-encoding.
How do I cut an MP3 online?
Add the file, drag across the waveform to select the part you want, preview it, then export. The trim runs in your browser — the file is never uploaded, and there is no length or count limit.
Can I make an iPhone ringtone with this?
Yes — select up to 40 seconds (iPhone's ringtone limit) and export as M4R, the format iPhones use. Transfer it to the phone with Finder (macOS) or iTunes (Windows) under Tones. Android just takes the MP3.
Can I cut audio out of a video?
Yes — drop an MP4 or MOV in, and the tool decodes its audio track just like an audio file. Trim and export as MP3; no separate extraction step needed.
Is my file uploaded?
No. Decoding, trimming, and encoding all happen in your browser tab. You can verify in the Network panel.
