MP3 cutter for Chromebook
Chromebooks don’t ship with an audio editor, and installing one through Linux is overkill for a single cut. This page runs in Chrome, reads the file straight from the Files app and saves the result to Downloads.

How to cut an MP3 on Chromebook
- Open the MP3 from Files. Click Open file and pick the MP3 from My files → Downloads or Google Drive — or drag it from the Files app onto the editor.
- Cut it. Drag the handles with the touchpad or type exact times. Click Zoom to selection to see the edges up close, and press Space to preview.
- Download. Click Download MP3. Chrome saves it to My files → Downloads; press Ctrl+J or open the tray notification to find it.
- Send it where you need it. Drag it to Google Drive in the Files app, or share it to your phone with Quick Share, to use as a ringtone or alarm.
Files on a Chromebook
Everything you download lands in My files → Downloads, which lives on the Chromebook itself. Files in Google Drive appear in the same Files app and open in the editor just like local ones — handy for a recording a phone uploaded. Double-click a downloaded MP3 to play it in the built-in media player and check the cut.
| Goal | How on ChromeOS |
|---|---|
| Open a song | Open file → My files, Downloads or Google Drive |
| Find the result | Files app → Downloads, or Ctrl+J in Chrome |
| Send to an Android phone | Right-click → Share → Quick Share, or move it to Google Drive |
| Send to an iPhone | Upload to iCloud Drive at icloud.com, then open it in the iPhone’s Files app |
Making a ringtone on a Chromebook
A Chromebook has no ringtone of its own, so the goal is to get the clip onto your phone. For Android, export MP3 (about 30 seconds), send it with Quick Share or Google Drive, then on the phone go to Settings → Sound & vibration → Phone ringtone and add it — the Android page lists the exact paths. For an iPhone on iOS 26, export MP3 or M4A under 30 seconds, upload it to iCloud Drive, then open it in Files on the iPhone and tap Share → Use as Ringtone. An M4R for computer sync needs Finder or iTunes, which ChromeOS doesn’t have.
Performance and formats
Encoding runs on the Chromebook’s own processor. A typical song cuts and encodes in a few seconds even on entry-level models; an hour-long recording needs more memory, so close other tabs first. MP3 and WAV always work. M4A and M4R depend on whether Chrome on your device offers an AAC encoder — if they are greyed out in the format menu, use MP3, which every phone accepts.
Want several pieces from one recording, such as the songs of a live set? Use cut MP3 into parts to export them all at once.

FAQ
Can I edit MP3s on a Chromebook without Linux?
Yes. This page runs entirely in Chrome. You don’t need the Linux environment, Audacity or an Android app to trim an MP3.
Where do downloaded MP3s go on a Chromebook?
To My files → Downloads in the Files app. Press Ctrl+J in Chrome to see recent downloads.
Can I open MP3s from Google Drive?
Yes. Google Drive appears in the file picker. The file is read into the browser for editing and is not uploaded anywhere else.
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.
