Free Online Audio Trimmer

Cut the exact part of a song you need. Choose a file, drag the handles on the real waveform or type timestamps, add an optional fade, preview the result and download it as MP3 or WAV. Your audio is processed on your device and never uploaded.

How to trim a song in your browser

  1. Choose a song. Select or drop an MP3, WAV, M4A or AAC file. MP3 and WAV open in every modern browser; M4A and AAC depend on the browser you use.
  2. Set start and end. Drag the two handles on the waveform, type exact times like 1:02.500, or use the 15s, 30s and 60s shortcuts.
  3. Fade and preview. Add a fade in or fade out if you want a softer start or ending, then play the selection. The preview is the same audio you'll download.
  4. Download. Pick MP3 or WAV and download. The file name includes the original name and the trimmed range.

Private by design

The trimmer reads your file with your browser's built-in audio engine. Decoding, cutting, fading and encoding all happen on your device, so your unreleased song isn't sent to a server.

  • No account or credits needed
  • No file upload
  • Works on desktop and mobile browsers

What you get in the download

WAV downloads are 16-bit PCM and keep the channel count and sample rate the browser reports for your file. MP3 downloads are 192 kbps; mono stays mono and stereo stays stereo.

  • MP3 is offered for standard rates up to 48 kHz; higher rates export as WAV
  • MP3 files can include a few milliseconds of encoder padding
  • Limits: songs up to 20 minutes on desktop and 10 minutes on phones and tablets — large files like WAVs are fine

Frequently asked questions

Is the audio trimmer really free?

Yes. It doesn't need an account, doesn't use TrackPush credits and doesn't add a watermark to the audio.

Is my song uploaded anywhere?

No. The file is opened and processed inside your browser. Nothing is sent to TrackPush servers while you trim.

Which file types can I open?

MP3 and WAV work in all modern browsers. M4A and AAC usually work in Safari and Chrome, but support depends on your browser. If a file won't open, convert it to MP3 or WAV first.

Which format should I download?

Choose MP3 for a small file that's easy to share or upload. Choose WAV if you'll edit the clip further, because WAV isn't compressed again.

Is there a file size or length limit?

Big files like full-quality WAVs are fine. The real limit is song length — 20 minutes on desktop and 10 minutes on phones — because the browser has to hold the whole decoded song in memory.

Does the preview include the fades?

Yes. The preview plays the exact trimmed and faded audio that gets downloaded.

Can I set times precisely?

Yes. Type times in minutes, seconds and milliseconds (for example 0:45.250), or select a handle and nudge it with the arrow keys: 0.1 seconds per press, or 1 second with Shift.
