Audio Cutter — Cut MP3 and Audio Online

Cut any song or recording down to the part you need. Open a file, drag the handles on the waveform or type exact start and end times, listen to the selection, and save it as an MP3 or WAV. Good for ringtones, intros, samples, and trimming silence. It runs in your browser, so the file is never uploaded and there's nothing to sign up for.

How to cut an audio file

Choose an audio or video file. It opens in your browser, so nothing is uploaded. Drag the handles on the waveform, or type exact start and end times. Press Play selection to hear the cut. If the edges sound abrupt, add a fade in or fade out. Pick MP3 or WAV and press Cut audio, then download the clip or turn it into a music video.

Make a ringtone from any song

A ringtone should start on something you recognise straight away, which is why most people pick the chorus. Select about 30 seconds, give it a 1-second fade in so it doesn't jump in mid-note, and a 2-second fade out so it ends cleanly. Save it as an MP3 at 192 kbps: it's small enough to send to your phone and sounds the same as the original through a phone speaker. Android phones take the MP3 directly as a ringtone. On iPhone, import the MP3 into GarageBand and share the project as a ringtone.

Cutting in the browser, without uploading

The cutter decodes the file with your browser's own audio engine, the same one that plays it, and slices the samples on your device. Nothing is sent to a server, so a private recording stays private and there is no queue. WAV output keeps the decoded samples unchanged; MP3 output is encoded again at the bitrate you choose. Need a different format afterwards? The audio converter turns the clip into MP3 or WAV, and the volume booster makes a quiet clip louder.

FAQ

How do I cut an audio file?

Open the file, then drag the two handles on the waveform to the start and end of the part you want, or type the times into the Start and End boxes. Press Play selection to check it, choose MP3 or WAV, and press Cut audio. The trimmed file appears below, ready to download.

How do I make a ringtone from a song?

Select about 30 seconds, usually the chorus, add a 1-second fade in and a 2-second fade out, and save it as an MP3. On Android, copy the MP3 to your phone and pick it in the sound settings. On iPhone, import the MP3 into GarageBand and share it as a ringtone; iPhone ringtones can be up to 40 seconds long.

Can I remove a part from the middle of a song?

Yes. Select the part you don't want and switch to Remove selection. The cutter joins the audio before and after it, with a ramp of a few milliseconds at the join so it doesn't click.

Can I cut the audio from a video?

Yes. Open an MP4 or MOV (or a WebM in Chrome or Firefox) and the cutter reads its audio track. Select the part you want and save it as MP3 or WAV; the picture is left out.

Does cutting reduce the quality?

WAV output keeps every sample exactly as it was decoded. MP3 output is encoded again, so pick 256 or 320 kbps when the source is already an MP3 and the difference stays inaudible. Each cut point gets a 5-millisecond ramp so the clip doesn't start or end with a click.

Is it free? Is my file uploaded anywhere?

It's free with no signup. The file is decoded and cut on your own device, so nothing goes to a server. The only limit is your device's memory: a very long file can be slow on an older phone. When the clip is ready, you can turn it into a music video with Solmi's AI music video generator.
