How to cut an MP3 on Android
- Open this page in Chrome. Chrome, Samsung Internet and Edge all work. Firefox works too but can only save MP3 and WAV.
- Choose the MP3. Tap Open file. In the picker, tap the menu (☰) or Browse and go to Downloads, Audio or Music, then tap the file.
- Trim it. Drag the handles on the waveform or type start and end times. Tap Play to check the cut; use a fade of 0.1 s or more to avoid clicks.
- Download. Tap Download MP3. Chrome saves it to the Download folder and shows an Open button at the bottom of the screen.
Where the cut file goes
Chrome for Android saves to Internal storage → Download. Open it later from Chrome’s ⋮ menu → Downloads, or in Files by Google (or My Files on Samsung) → Downloads. Music players and the ringtone picker scan this folder, so you don’t need to move the file.
Set the cut as your ringtone
| Phone | Path |
|---|---|
| Google Pixel and stock Android | Settings → Sound & vibration → Phone ringtone → My Sounds → + |
| Samsung Galaxy (One UI) | Settings → Sounds and vibration → Ringtone → + at the top |
| Notification sound | Settings → Sound & vibration → Default notification sound |
| One contact only | Contacts → the contact → ⋮ or Edit → Set ringtone |
Menu names vary slightly between brands and Android versions; if you can’t see the file, look for an Add or Custom option and browse to Downloads. Pixel phones copy the tone into their own ringtone list; on some other brands the ringtone falls back to the default if the original file is moved or deleted, so leave it where it is. Android has no fixed length limit — the phone simply loops or stops the file — but 20–30 seconds starting on the chorus works best. The Android ringtone maker selects the loudest 30 seconds automatically, and the Android ringtone guide covers more phones.
Why use a browser instead of an app?
Most “MP3 cutter” apps on Google Play are ad-supported and ask for access to all your media. This page asks for nothing: Chrome only gives it the single file you pick, and it never uploads it. Once the page has loaded, it even works offline.
- Turn the phone sideways for a wider waveform.
- Tap Zoom to selection to fine-tune a cut point.
- 192 kbps MP3 is plenty for a ringtone; ringtone files are only about 0.7 MB.

FAQ
Can I cut an MP3 on Android without an app?
Yes. Open this page in Chrome, tap Open file, pick the MP3, select the part you want and tap Download. Nothing is installed or uploaded.
Where are my cut MP3 files saved on Android?
In the Download folder of your internal storage. Find them in Chrome’s Downloads list or in the Files app under Downloads.
Why doesn’t my new ringtone show in the list?
Use the + or Add button in the ringtone screen and browse to Downloads; some phones don’t list new files until you add them that way. Restarting the Settings app also refreshes the list.
Are my files uploaded?
No. Audio is decoded, edited and encoded in your browser with the Web Audio API, WebCodecs and a JavaScript MP3 encoder. Nothing is sent to a server, so it also works on slow connections once the page has loaded.
