Chromebooks don't come with a desktop audio converter, and you can't install the usual Windows or Mac programs. That's less of a problem than it sounds: a browser-based converter does the job well, and for heavier work there's an optional Linux route. This guide covers both, plus where ChromeOS keeps your files.
Why converting on a Chromebook is different
- No Windows or Mac apps. Programs like the Windows desktop version of VLC or Audacity don't run on ChromeOS directly.
- Android apps vary. Many Chromebooks can install Android apps from Google Play, but converter apps are often full of ads or ask for broad permissions.
- Files are often in the cloud. Many Chromebook users keep files in Google Drive, so you need to know how to pick them.
- Some models have little memory. Entry-level Chromebooks can slow down with very large files.
A browser-based converter sidesteps the first two issues and works on any Chromebook with a recent version of Chrome.
Where does ChromeOS save your files?
Everything is in the Files app (press the Launcher key and type "Files"):
| What | Default location |
|---|---|
| Downloads from Chrome | My files > Downloads |
| Screen recordings | My files > Downloads (or the folder set in Screen capture settings) |
| Google Drive files | Google Drive > My Drive in the Files app sidebar |
| Files from a USB drive or SD card | The drive's name in the sidebar |
| Files from an Android phone | Via Phone Hub or a USB cable, depending on your setup |
How to convert a file to MP3 on a Chromebook
- Open the MP3 converter in Chrome.
- Click to choose a file. The Files picker opens; browse to Downloads, Google Drive or a USB drive.
- Pick a bitrate:
- 128 kbps for speech (lectures, meetings, voice notes). - 192 kbps for everyday music (the default). - 256 or 320 kbps for music you care about.
- Click Convert to MP3 and wait for the progress bar.
- Click Download MP3. You'll find it in My files > Downloads.
Files can be up to 150 MB, one at a time. For a video, the converter keeps the first audio track and drops the picture.
Format shortcuts
- Video from a phone or camera: MP4 to MP3
- iPhone recordings or Apple audio: M4A to MP3
- Uncompressed audio: WAV to MP3
- Chromebook screen recordings and web video: WebM to MP3
The general converter also takes MOV, MKV, AAC, FLAC, OGG, OPUS and MPEG files.
Converting a Chromebook screen recording
ChromeOS has a built-in screen recorder in Screen capture (in Quick Settings, or press Ctrl + Shift + Show windows). Recordings are typically saved as WebM video files.
To keep only the audio:
- Make sure the recording captured sound. In Screen capture settings, turn on the microphone if you need your voice, and check whether your version of ChromeOS offers to record system audio.
- Find the recording in Downloads.
- Convert it with WebM to MP3.
If your recording has no sound, the MP3 will be silent: the converter can't add audio that wasn't recorded. The screen recording to MP3 guide covers this on other devices too.
Converting files stored in Google Drive
You can pick Drive files directly from the file picker, but a few tips help:
- Make large files available offline (right-click in the Files app > Available offline) before converting. That avoids waiting on a slow connection while the file loads.
- Google Docs-type files (Docs, Sheets) aren't audio and can't be converted; only real audio and video files work.
- Save the MP3 back to Drive by moving it from Downloads into a Drive folder in the Files app.
What about very large files?
If a file is bigger than 150 MB, or your Chromebook struggles with it:
- Close other tabs so Chrome has more memory to work with.
- Trim the video first. Some Chromebooks include a video editor, and web-based editors work too.
- Split the file into shorter parts and convert each.
- Use Linux (advanced). Many Chromebooks support a Linux development environment (Settings > About ChromeOS > Developers). With it, you can install desktop tools such as Audacity or ffmpeg. This takes some storage and a little comfort with the command line.
Our guides for Windows and Mac cover those desktop tools in more detail.
What about Android converter apps?
They can work, but check before installing:
- Permissions: an audio converter doesn't need your contacts or location.
- Ads and upsells: many free converter apps are ad-heavy or lock higher bitrates behind a subscription.
- Where processing happens: some apps upload your file to a server; others convert on the device.
For occasional conversions, the browser is usually simpler.
Playing MP3 files on a Chromebook
Double-click an MP3 in the Files app and it opens in the built-in media app. To use the MP3 elsewhere, copy it to a USB drive, move it to Google Drive or attach it to an email.
Troubleshooting
| Problem | What to try |
|---|---|
| The file picker doesn't show my file | Check Google Drive and USB drives in the sidebar; make sure the file finished downloading |
| The conversion is very slow | Close other tabs, or make the Drive file available offline first |
| "File too large" | Trim or split the file, or use the Linux route |
| The MP3 is silent | The source had no audio, or the screen recording didn't capture sound |
| AVI or WMA files are rejected | Those formats aren't supported; convert them with a desktop tool on Linux |
