Is there a file size limit?

No fixed limit. The work happens in your browser, so the practical ceiling is your device’s memory, not an upload cap.

Can I cut a part out of the middle?

Yes. Select the part you don’t want and choose Remove selection. Everything before and after it is joined, with a tiny crossfade so the join doesn’t click.

Can I make a ringtone with it?

Yes. Select up to 40 seconds and export as iPhone ringtone for an .m4r file, or as MP3 for Android. A longer selection is refused before anything is encoded.

Can I cut the audio from a video?

Yes. Open an MP4, MOV or WebM file and its soundtrack opens as audio. Export it as MP3, WAV or any other format.

Will cutting re-encode my MP3?

Exporting to MP3 re-encodes, so it goes through one more round of lossy compression. Export to WAV or FLAC if you want to avoid that.

How precise can the cut be?

Type the start and end times into the fields rather than dragging, and loop the selection to check each edge by ear.

Why is there a click at the start of my clip?

The cut landed in the middle of a sound wave. Switch on Fade in or Fade out; a few tenths of a second removes it.

Can I use it on my phone?

Yes. The waveform works with touch, and you can type exact times if dragging is fiddly on a small screen.

What it does

Keep the part of a song or recording you want, or cut out the part you don’t: a ringtone, the intro for a video, a cough in the middle of an interview. Drag the edges of the waveform, or type the exact start and end times.

Keep or remove. Keep just the selection, or remove it and keep everything else, joined without a click.
Fade in and fade out, set in seconds, so a clip starts and ends smoothly.
From a video too. Open an MP4, MOV or WebM clip and cut its soundtrack. MP3, WAV, FLAC, M4A and OGG open as well.
Loop plays the selection over and over while you fine-tune the edges.
History keeps every change, so you can step back to any earlier selection.
Saves as WAV, MP3, FLAC, M4A or an iPhone ringtone, under a name you can edit.

How to cut an MP3

Choose your file, or drag it onto the box above.
Drag the dark edges of the waveform to the start and end of the part, or type the times in Start and End.
Choose Keep selection to keep that part, or Remove selection to cut it out.
Press Play to hear the result; click anywhere on the waveform to listen from that point.
Press Export and pick a format.

Cutting mid-sound can leave a click at the edge. Switch on Fade in or Fade out — a few tenths of a second is enough.
