Cut MP3 and Make Ringtones Online

Trim an MP3 to the exact second, fade it in and out, and export it as a ringtone your phone will actually use — M4R for iPhone, MP3 for Android. You can even drop in a video and keep only its sound.

What it is for

Three Things People Cut Audio For

One tool, three everyday jobs. Pick a range on the waveform, preview just that part, and export.

Trim an MP3

Keep the chorus, drop the silence at the start, or grab a single line. The cut is precise to the millisecond because the audio is always re-encoded, not roughly copied.

Make a ringtone

Export M4R for iPhone or MP3 for Android. A fade out stops the ringtone ending abruptly, and the page warns you if an iPhone ringtone runs past 40 seconds.

Grab audio from a video

Drop in an MP4 or MOV and the picture is dropped, leaving just the sound. Handy for pulling a quote or a piece of music out of a clip.

Formats and quality

Every Format You Are Likely to Need

  • MP3 at 128, 192 or 320 kbps — the safe default that plays everywhere.
  • M4R — the iPhone ringtone format. It is the same AAC audio as M4A, just with the extension iOS looks for.
  • M4A, WAV and OGG for when you need lossless, or a specific container.
  • Fade in and fade out up to three seconds each, so clips start and end cleanly instead of clicking.

Ringtones

Getting the Ringtone Onto Your Phone

iPhone (M4R)

Cut the clip to 30 seconds or less and export M4R. On a computer, open Finder (or iTunes on Windows), connect the iPhone and drag the .m4r file across — or use GarageBand on the phone to share it as a ringtone. Then pick it under Settings › Sounds & Haptics › Ringtone.

Android

Export MP3 and copy it into your phone's Ringtones folder over USB or with a file manager. Open Settings › Sound › Phone ringtone and choose your file — many phones let you add it directly with a “+”.

Privacy

Your File Is Deleted After Cutting

  • Cutting runs on Bubixo's own server with FFmpeg, so the tool works the same on any phone or computer without installing anything.
  • The file you upload is used only to make the cut, then the source is deleted as soon as processing finishes. Generated clips are kept for a limited time and never shared.
  • No account and no sign-up — the tool is free to use.

Step by step

Cut Audio in Three Steps

1 · Choose the file

Drop in an audio file — MP3, WAV, M4A, AAC, OGG or FLAC — or a video to grab its sound. The waveform appears so you can see where to cut.

2 · Set the range

Drag the two handles or type exact times, and press play to preview only the selection. Add a fade in or out and choose the format.

3 · Cut and download

The server renders the clip and it downloads straight away, ready to use as a ringtone or share.

Frequently asked questions

Audio Cutter FAQ

Can I make an iPhone ringtone with this?

Yes. Export the M4R format, which is the ringtone format iOS uses. Keep it to 30 seconds to be safe (the page warns you past 40 seconds), then transfer it with Finder, iTunes or GarageBand.

Is the cut accurate to the second?

Yes, to the millisecond. The audio is re-encoded rather than roughly copied, so the start and end land exactly where you set them and fades are applied cleanly.

Can I take the audio out of a video?

Yes. Drop an MP4 or MOV file in and the video is discarded, leaving only the sound to cut and export.

What formats can I export?

MP3 (128, 192 or 320 kbps), M4R, M4A, WAV and OGG. MP3 is the safe default; M4R is for iPhone ringtones; WAV is lossless.

Is my file uploaded somewhere?

The file is sent to Bubixo's own server to be cut, because the cutting is done with FFmpeg. The source is deleted the moment processing finishes, nothing is shared, and no account is needed.

Why can't I open an iTunes .m4p file?

Files bought from the iTunes Store as protected .m4p are DRM-locked and cannot be opened by any editor. Use a DRM-free MP3, M4A or AAC file instead.

Bubixo audio tools are free to use.
