How to cut an audio file
- Choose your file — MP3, WAV, M4A, AAC, OGG or FLAC (anything your browser can play).
- Move the Start and End sliders. The selected part is highlighted on the waveform; press Play selection to hear it.
- Optionally add a fade in or fade out for a smooth start and finish.
- Choose MP3 or WAV and press Cut & download.
Making a ringtone
- Android: cut a 20–30 second MP3, copy it to your phone’s Ringtones folder (or open it and choose “Set as ringtone”).
- iPhone: ringtones must be under 30 seconds and in .m4r format, added via GarageBand or Finder/iTunes. Cut the clip here as WAV, then import it into GarageBand on your iPhone and export as a ringtone.
- Add a short fade in (1–2 seconds) so the ringtone doesn’t start abruptly.
MP3 or WAV?
MP3 is compressed: a 3-minute song at 192 kbps is about 4 MB and plays on every device. WAV is uncompressed (about 30 MB for the same length) and loses no further quality — choose it if you will edit the audio again. Note that cutting an MP3 and saving it as MP3 re-encodes the audio once; at 192 kbps the difference is inaudible for most listeners.
Other uses
- Remove silence or mistakes from the start and end of a voice recording.
- Clip a quote from an interview or podcast.
- Prepare intro and outro music for videos.
- Extract a section of audio from a video — first use Video to MP3.

Frequently asked questions
Which audio formats can I cut?
Any format your browser can decode — usually MP3, WAV, M4A/AAC, OGG and FLAC. Opus and WebM work in Chrome and Firefox.
Can I set exact start and end times?
Use the sliders; the exact times are shown next to each slider to a tenth of a second.
Is there a file size limit?
No fixed limit, but very long files (over an hour) need a lot of memory, especially on phones.
Are my files uploaded?
No. Cutting and encoding happen in your browser.
