This free audio trimmer, also called an MP3 cutter, shortens a song or recording to the part you want. It shows the whole file as a waveform, so loud parts, quiet gaps and silence at the start or end are easy to spot before you cut.
Keep a part, or cut a part out
- Keep the selection trims away everything before the start handle and after the end handle. Use it for a ringtone, a clip to share, or a sample.
- Cut out the selection removes the part between the handles and joins what comes before and after with a 10 millisecond crossfade, so the join does not click. Use it to take out a mistake, a pause or an advert break.
Choosing the format to save
| Save as | Best when |
|---|---|
| MP3, 320 kbps | You started from an MP3 or M4A and want to keep as much quality as possible |
| MP3, 192 kbps | Everyday listening and sharing, at a smaller size |
| MP3, 128 kbps | Speech, voice memos and the smallest files |
| WAV | You started from WAV or FLAC, or will edit the audio further; nothing more is lost |
| OGG | A game, app or program asks for OGG |
Tips for a clean cut
- Start and end cuts in a quiet moment, where the waveform is thin, and they will sound natural.
- If a cut still ends too suddenly, add a short fade out of 0.5 or 1 second.
- Use Play the last 3 seconds to check the ending without listening to the whole selection.
Only edit audio you made or have the right to use. Cutting a song does not change who owns it.

Questions
How do I cut an MP3 file?
Choose the MP3, drag the handles on the waveform to the start and end of the part you want, press Play selection to check it, then press Save trimmed audio. The shorter MP3 downloads straight away.
Can I remove a part from the middle of a song?
Yes. Select the part you do not want, choose Cut out the selection and save. The sound before and after is joined with a very short crossfade, so there is no click where the cut was. Press Play around the cut to hear the join first.
How exact can the cut be?
To a tenth of a second. Type the times in the Start and End boxes, for example 1:23.4, or select a handle and use the arrow keys to move it 0.1 seconds at a time.
Does trimming an MP3 lower its quality?
Saving as MP3 again compresses the sound a second time, which loses a little detail. Choose MP3 at 320 kbps to keep the most, or WAV to lose nothing more at all. Trimming a WAV or FLAC file and saving it as WAV keeps every sample exactly.
Can I make a ringtone?
Yes for Android: trim the part you want to about 30 seconds, add a short fade in and out, and save it as MP3. iPhone ringtones use a different file type that has to be set up with GarageBand or a computer, so this tool cannot make one directly.
Can I trim a voice memo or voice message?
Yes. iPhone voice memos (M4A) and voice messages saved as OGG or Opus open here. Cut out the silence or the part you do not need and save it as MP3.
Why can I not hear the fade when I play the part around a cut?
Fades apply to the very start and end of the saved file. Play selection plays them when you keep a part; when you cut a part out, the fades are added to the start and end of the whole file when you save.
Are song details and album art kept?
No. The new file holds the sound only, so title, artist and cover art are not copied. Most music apps let you add them again.
Is my audio uploaded?
No. The file is opened, cut and saved by your browser on your own device, and it is never sent to us or anyone else.
Is it free?
Yes, completely free, with no sign-up, no watermark and no limit on file length.
