How to Cut an MP3 Online for Free (Exact Times, Fades, No Upload)

To cut an MP3, open the free MP3 Cutter, drop your file, drag the two handles on the waveform (or type the start and end times), then click Cut and save MP3. The cut happens inside your browser, so the song never leaves your device and there is no sign up or watermark.

Below: the exact steps, how to make a clean cut that does not click, which format and bitrate to choose, and how to turn the clip into an iPhone ringtone.

How to cut an MP3 online (step by step)

1. Open MP3 Cutter in any modern browser on a computer or phone.
2. Drop your audio file onto the page, or tap to pick it. The tool reads it and draws a waveform, so you can see loud and quiet parts at a glance.
3. Drag the left handle to where the clip should start and the right handle to where it should end. You can also click on the waveform: the nearest edge jumps to that point.
4. For an exact cut, type the times into the Start and End boxes, for example 1:05.5 and 1:35, and press Enter.
5. Press Play selection to hear only the part you picked. Adjust and listen again until it sounds right.
6. Under Output, choose a format (MP3, M4A or WAV), a bitrate, and an optional fade in or fade out.
7. Click Cut and save MP3, then download the file. The result shows its size, length and how long the cut took.

The tool also shows an estimated size before you cut, which helps when the clip must fit an upload or messaging limit.

Which files can the MP3 cutter open?

Despite the name, it is a general audio cutter. It opens MP3, WAV, M4A, AAC, OGG, Opus and FLAC files, and it can take the sound track out of video files such as MP4, MOV, MKV and WebM. That last part is handy when the music you want is inside a video: drop the video and cut the audio straight from it.

If you want the whole soundtrack of a video rather than a part, Extract Audio from Video is quicker, and our guide on how to extract audio from a video explains the options.

How to make a clean cut that does not click

A cut in the middle of a sound can produce a small click or an abrupt start. Three habits fix almost every case:

• Start on a quiet point. Look at the waveform and place the start handle where the wave is thin, between words or beats, not on a peak.
• Add a short fade. A 0.5 second fade in removes the click at the start without changing how the clip sounds. Use a 2 or 3 second fade out when you stop in the middle of a song, so it ends gently instead of being chopped.
• Listen before you save. Play selection costs nothing and catches a cut that lands half a word early.

Fade options are 0, 0.5, 1, 2 and 3 seconds for both the start and the end. A fade can never be longer than half the clip, so very short clips still work.

Which format and bitrate should you choose?

The cutter decodes your file and saves a new one, so the output settings decide the final quality and size.

Use	Format	Bitrate	Why
Music you will keep	MP3	256 or 320 kbps	Near the source quality for most songs
Everyday clips, sharing	MP3	192 kbps (default)	Good quality at a moderate size
Voice notes, podcasts	MP3	128 kbps	Speech sounds fine and files stay small
iPhone ringtone, Apple apps	M4A (AAC)	128 to 192 kbps	AAC is what Apple devices expect
Editing in another program	WAV	16 bit PCM	No compression, so no extra quality loss

One honest rule: saving can not add quality that was never there. If your source is a 128 kbps MP3, picking 320 kbps only makes the file bigger. Match or stay a little above the source bitrate. The MP3 format is lossy, which is why every re save should use a sensible bitrate rather than the lowest one.

The output is stereo. Files with more channels, such as a 5.1 movie soundtrack, are mixed down to two channels, which is what phones, speakers and messaging apps play anyway.

How to cut an MP3 into a ringtone

Ringtones are short, so switch on Limit to 30 seconds (ringtone) under Output. The selection then can not grow past 30 seconds while you drag.

• Android: keep MP3, cut the chorus, add a 1 second fade out, and save. Then pick it as the ringtone in your phone's sound settings.
• iPhone: choose M4A (AAC). After cutting, a second button appears: iPhone ringtone (.m4r). Download that file and add it to your iPhone's tones with a computer (Finder on a Mac, or iTunes or the Apple Devices app on Windows).

Tip: start the ringtone a beat before the part people recognise, so the first ring is not half a second of silence.

Is it safe to cut audio online?

Most online cutters upload your song to their server before they can cut it. This one does not. The waveform, the preview and the final encode all run in your browser with Web Audio and a built in encoder, so the file stays on your device. That matters for private recordings such as interviews, meetings or voice messages. It also means there is no file size cap set by an upload limit; very long files simply need a device with enough memory.

Common MP3 cutting mistakes

• Cutting on a loud peak. It causes a click. Move the edge to a quiet spot or add a 0.5 second fade.
• Picking the highest bitrate for a low quality source. It wastes space with no audible gain.
• Forgetting to preview. Play selection first; re cutting later takes longer than listening once.
• Converting when you only need a part. If you need a different format of the whole file, use a converter such as MP4 to MP3 instead.

Frequently asked questions

How do I cut part of an MP3 file for free?

Open the WoowTools MP3 Cutter, drop the file, drag the handles on the waveform or type the start and end times, and click Cut and save MP3. It is free, has no watermark and does not need an account.

Can I cut an MP3 without uploading it?

Yes. The WoowTools cutter decodes and encodes the audio inside your browser, so the file never leaves your device. That keeps private recordings private and avoids upload waits.

Does cutting an MP3 reduce the quality?

Saving a new MP3 encodes the audio again, which can lose a little detail at low bitrates. Choose a bitrate equal to or a bit above your source, or save as WAV if you will edit the clip further.

How do I cut an MP3 on my phone?

Open the MP3 Cutter in Chrome or Safari on your phone, pick the file from Files or Downloads, drag the handles, preview and save. The same steps work on Android and iPhone.

How do I make a ringtone from an MP3?

Turn on Limit to 30 seconds, select the part you want and add a short fade out. Save as MP3 for Android, or choose M4A and download the iPhone ringtone (.m4r) file for an iPhone.
